Megafon modem dns server is not responding. The DNS server is not responding. Changing DNS servers in network card settings

Sometimes after rebooting the computer, or even for no obvious reason, instead of home page favorite site, a frightening message “Server dns address not found” is displayed (sometimes the message is even more succinct “Error dns server A").

And in this article we will look at why the dns server does not respond, and what to do when Windows OS cannot find the dns address of the server.

Cannot find server dns address: possible causes of the problem

Among the most common causes of DNS server errors are:

1. Engineering works on the site itself or on the side of the ISP that “hosts” the Internet resource.

2. Technical work on the side of your Internet provider.

3. Network settings on your computer have failed.

If a DNS server error “pops up” only on one site (and the rest of the web pages “load” without problems), then the problem is most likely on the side of this web resource and there is nothing you can do here: for sure, site administrators know about problems and will fix the problem as soon as possible.

If the DNS server is unavailable on several sites, then it is worth checking the loading of these resources from other computers/mobile devices: if the unfortunate error occurs on all PCs, then this is either a problem with the provider or a problem with your network device (for example, a router).

In this case, you should trust the complex network magic using auto-tuning and:

1. Turn off the power to the router, wait 30 seconds and turn on the router again.

2. Remove the network cable from the LAN port of the computer and reconnect the connector to the connector network card.

3. Restart your computer.

In most cases, after such “operations” Windows is able to find the dns address of the server, and your favorite sites work without problems.

If the browser still writes that the DNS server is not responding, then you will have to “uncover the heavy artillery.”

There are several other possible reasons for this error:

1. Viruses that automatically change network settings Windows 7 OS.

2. An unlucky wizard who manually set .

3. Crashed after removing any system/network programs DNS settings or problems with the DNS service starting automatically.

How to fix the “DNS server unavailable” error?

1. DNS cache is a data storage on your computer in which the names of sites are recorded - this is necessary to speed up the connection to the desired resource. Perhaps clearing the cache will help - to do this, press “Win” + “R”, run the command “ipconfig /flushdns” in the terminal and try to access the site again.

2. If updating the cache did not help, you will have to manually register the DNS servers - most likely, these are problems on the provider’s side. To do this, open the terminal again command line via “Win” + “R” and execute “ncpa.cpl” - the “Network Connections” menu will open.

2.1. Select the one that is used to access the network -> Properties -> Internet Protocol Version 4 -> Properties.

2.2. If something is indicated in the “Primary” and “Alternative” servers, try checking the “Receive DNS data automatically” box, apply the changes and reboot.

2.3. If initially there was a checkbox for automatic retrieval, then in the “Preferred DNS server address” indicate “8.8.8.8”, and in the “Alternative” - “8.8.4.4”.

So, you have specified Google Public DNS servers that work flawlessly. Apply the settings, restart your computer and try connecting to the desired site again.

If the computer cannot find the DNS server address when connecting through a router (and not directly), you need to find it in the tab with DNS servers and specify the same two addresses there. If there are more fields for addresses or other addresses are specified, do not be alarmed, just specify two addresses and save the settings.

3. If this does not help, perhaps the error appears due to a virus.

In this case, a full system scan with antivirus software, such as Dr.Web, Avira, Avast or Kaspersky, will help.

4. Check if the autostart of the DNS service works correctly. To do this, go to Control Panel -> Administration -> Services,

Find the DNS service in the list and check if “Automatic” is listed in the “Startup Type” column.

5. If after all the above measures the problem “cannot find the dns address of the server” is not resolved, you will need to reset the TCP/IP settings on the computer. Here you will find free utility from Microsoft and user instructions - https://support.microsoft.com/ru-ru/kb/299357

Internet users sometimes encounter situations where they are unable to access the network. The error “DNS server is not responding” often occurs. Difficulties will not arise if you know the causes of the problem and how to solve them.

What is the error and why does it occur?

Each Internet resource has its own IP address, from which the DNS server redirects requests to the domain. If access to the servers is closed, then when you try to go online, a window with the error “DNS server is not responding” appears, and on the taskbar you can see yellow triangle With exclamation mark inside.

Solution methods

If there is no debt to the provider and the equipment is operational, then the malfunction can be eliminated in several ways. But first you need to find out the cause of the problem.

Checking the DNS client service

In the operating room Windows system 7, 8, 10 there is a special service that is responsible for the correct operation of the DNS server. First, check it out:

Checking connection properties

If, after setting up the service, Internet access does not appear and the DNS error does not disappear, then check the connection properties and change the settings if necessary:


Clearing the DNS cache

There is another way to configure the server - clearing the cache. Usually, they use the command line for this, which can be called up by simultaneously pressing the Win and R keys. After which:


Checking for viruses

Sometimes the antivirus blocks access to the Internet. This problem may be caused by a virus, in which case scan the system for availability malware. But there are situations when the antivirus itself, due to incorrect settings does not allow access to some sites or even completely blocks the server. To check this possibility, disable your security software for a few minutes and go online. If it works, then you need to look for the problem in the settings of your antivirus program.

Firewall is blocking the connection

A firewall serves to protect your computer by closing sites and resources that it considers harmful. Due to incorrect settings, it can also block DNS servers. Disable it for a while to check if this is the cause. The built-in firewall can be turned off by going to control Panel. Choose " Windows and security", then " WindowsFirewall" Convert all values ​​to " DisableFirewall» and click OK.

Problems with network card drivers

For correct operation, all connected devices must be installed drivers with latest updates . Because of outdated drivers network card, access to the network is also limited. To update them, you can use special utilities, for example, Driver Booster. Just download it and run it. The program will find the necessary drivers and direct you to links with updates.

Computer or router errors

May I help reset computer (PC) and router. First, disconnect the router from the network and leave it for a few minutes. Then restart your PC and turn on the router again.

Problems with the provider

If none of the methods helped fix the error “DNS server or resource is not responding,” then it is better to contact provider's technical service. The connection problem is probably due to an Internet outage. Specialists should help solve the problem.

Using DNS Jumper

To resolve the “DNS server is not responding” error, you can also use special program to configure DNS Jumper. It doesn't require installation. By launching the utility it is possible enter the server manually or let the program choose it itself. She will choose the fastest and a normally working server. Addition DOTVPN It also allows you to select the country from which you can access the network.

Possible problems with the TP-Link router

Users very often use TP-Link routers. But some devices periodically settings are lost. Therefore, the access error can be resolved by resetting the router to factory settings and re-entering the necessary parameters.

If you get to the root of the problem, it can be solved. It is not necessary to call a technician for setup or take the computer to a service center.

The “DNS server is not responding” error may indicate both problems with your computer and more global problems.

Now we will list everything that a user can do in such a difficult situation.

Simple ways to solve the problem

Sometimes a problem that seems very complex can be solved quite simply.

Here's what you need to do from the very beginning:

  • Restart your computer. Finding the true cause of this error can be quite difficult. It is quite possible that some operating system parameters are preventing it from connecting to the Internet. Therefore, it is better to start it again.
  • Reboot your router. The same goes for the router - some parameters get lost from time to time. You can try to find them and configure them correctly, or you can simply start the system again. The second option is faster. Just unplug the router from the socket and turn it on after a minute.
  • If the Internet does not come through the router, but directly through the cable, check its integrity. If possible, it is better to even go up to the roof of the house to see what is wrong with the wires - often, for example, hooligans cut them for some reason. If there is damage somewhere, it is better to replace or isolate this area.
  • If you do connect through a router, try connecting directly. This way you can understand what the real problem is. If the connection is restored when connecting directly, try using a different router. This will make it possible to make sure that the problem is really in the old router.
  • Just wait a while. It is quite possible that the provider is doing some work or for some other reason the connection is temporarily unavailable. Then you just need to wait a little.

Tip: Call your ISP if you have any problems with the Internet. Now many providers report that, for example, they are working at your address and after some time (usually the operator says how long) the connection will be restored. Then you won’t have to worry about specified time check your internet.

This is the simplest thing you can do. Most often you have to do something more complex.

Restarting the service

Rebooting the DNS client often helps. This is done as follows:

  • Press the “Win” and “R” buttons on your keyboard at the same time, or launch the command window (aka “Run”) from the Start menu. In it, enter the command “services.msc” and click “OK”.
  • The operating system services window will open. In the list you need to find the DNS client, click on it right click mouse and select “Properties” in the drop-down window.
  • In the properties window, next to “Startup type”, set “Automatic”. Next, click “Start” to restart this service.
  • Restart your computer.

This should help. And if nothing has changed, move on to the next way to solve the problem.

Server settings

It happens that certain settings for connecting to the server, for example, its address, are lost. Therefore they need to be corrected.

This is done like this:

  • Click on the connection icon in the tray (bottom right) with the right mouse button. In the drop-down menu, select “Network and Sharing Center...”.
  • In the window that opens, click “Change settings...” in the left panel.
  • On the connection you are using, right-click and select “Properties” from the drop-down menu.
  • In the window that opens, left-click once on the item “IP version 4 (TCP/IPv4)”. A little lower, click the “Properties” button.
  • To put it simply, there should not be any addresses in the next window. Check the two boxes “Obtain an address automatically”, click “OK”, restart your computer and try to connect again.

If setting the automatic receipt of addresses did not help, try setting the Google server addresses to 8.8.8.8 and 8.8.4.4.

This should be entered as “Preferred DNS Server” and “Alternate DNS Server” respectively.

Clearing cache

When connecting to DNS, a lot of different information is accumulated, in other words, a cache.

You should get rid of it, like any other type of cache.

The same applies to various temporary network parameters.

Fortunately, this can be done very simply - you only need to enter 4 commands:

  • ipconfig /flushdns
  • ipconfig /registerdns
  • ipconfig /renew
  • ipconfig /release

They should be entered into the console, which is launched by entering the “cmd” command into the command execution window.

Let us remind you that it opens by pressing the “Win” and “R” buttons.

After entering each command, press Enter to execute it.

Driver Update

In some cases, updating network card drivers helps. This is done as follows:

  • From the Start menu, type Driver Manager in the search bar. Run the found program.
  • Find the section " Network adapters" There may be several devices. It's best to follow these steps for each of them.
  • Right-click on the device and select “Update Drivers”.
  • In the update window, first select automatic search drivers. If the necessary files are found, install them. And if all else fails, try finding drivers for the selected device on the Internet. To do this, simply enter a query like “[Device name] drivers.” Then click "Browse this computer for driver software." If the system cannot find them, specify the path to the files manually.

It is advisable to restart your computer after this. But the Internet can be restored even after a regular update.

Disabling utility programs

The computer may have certain programs installed that work with the Internet.

They can use certain ports, some completely block the connection to the Internet or filter or limit it in some way.

For example, many antiviruses have a parental control feature.

It allows you to “detect” in time and not open sites that contain inappropriate materials (pornography, violence, etc.).

Of course, in order to perform this function, the antivirus must have access to the connection.

Another example is a firewall. It literally filters all materials that reach the user.

But in some cases such programs do not work correctly. For example, they can completely block the Internet, despite the fact that the user did not give them such a task.

Some settings may be lost.

Therefore, all programs that are somehow connected to the Internet should be temporarily disabled.

But it is important not to turn off all of them at once. In this case, you will not be able to find the culprit. It is better to disconnect them one by one and see if the connection is restored.

The antivirus usually turns off easily - right-click on its icon in the tray and select “Exit” or “Disable”. The figure below shows this process for Kaspersky Anti-Virus.

The same goes for many other Internet-related programs. They all involve creating a tray icon.

If this is not the case, go directly to the entire program and look for the shutdown button there.

As for the firewall (aka firewall), to turn it off, do this:

  • From the Start menu, open Control Panel.
  • In it, open “Windows Firewall”.

This article will discuss the situation when, when connecting to the Internet, the system reports that the DNS server is not responding. Fixing this problem is quite simple; all you need to do is follow the recommendations from the article.

To fix the problem you will need to follow these instructions:

1. Open Start and go to Control Panel.

2. In the new window, go to the "Administration" section, and then open the "Services" link.

3. Find “DNS Client” in the list of services and check if this service is running. If not, right-click on it, and then go to “Properties”.

4. In the window that appears, in the “Startup type” column, select the “Automatic” option. Save your changes before exiting.

If everything is fine with this service, then you additionally need to perform some more actions:

1) Open Start and go to Control Panel. Open the "Network and Sharing Center" section shared access».

2) In the new window, pay attention to the right side and open the “Change adapter settings” menu.

3) Right-click on your Internet connection and select “Properties”.

4) In the list of components we need “IP version 4 (TCP/IPv4)”. Select it with one click, and then click the activated “Properties” button.

5) More than likely, in the window that opens you will have the option “Obtain DNS server address automatically” checked. It needs to be changed to “Use the following DNS server addresses.”

6) In the “Preferred DNS Server” column, enter 8. 8. 8. 8, and in the “Alternative DMS Server” column, enter 8. 8. 4. 4. These parameters are the public addresses of Google servers.

If these actions do not bring results, then there may be a problem in the operating system. You can perform a system rollback to the restore point when the problem did not yet make itself felt. To do this, open “Start” and use the search to find the “System Restore” menu. Open it and roll back the OS. Please note that after performing the restore, the computer will need to be rebooted.

What to do if the DNS server does not respond?

When the DNS server does not respond, it’s a shame not to know what to do. After all, all the equipment is in good order, there are funds on the balance sheet. But there is no Internet itself due to a banal error in the settings. At the same time, you cannot complain about a breakdown of your laptop or computer, the modem is in perfect order and the provider itself has no problems. But don’t worry, the settings change within a minute and are updated almost instantly. This will be discussed below.

Why are DNS servers needed?

Before moving on to the problem, you need to understand what DNS servers are. By accessing any page located on the network, you gain access to a specific section of the remote server. This directory stores files that the browser interprets and provides information to you in the form of an information page. Each server has its own IP address, which is used to gain access. This practice was convenient when the Internet was a network of several dozen servers. The set of numbers was ideal for scientists accustomed to strict consistency and hierarchy of data. But as soon as the Internet went beyond the laboratory and became an entertainment public network, there was a need for some other way to identify sites. In order to meet the growing demands of the audience, domains consisting of Latin characters were introduced. Several years ago, their Cyrillic counterparts appeared for visitors from the CIS.

Watch a video about how DNS servers work:

DNS servers exist to correctly redirect from IP to domains.

What problems might arise?

Who most often has problems with servers? Most susceptible to it are modem owners who do not want or cannot switch to the connection option using network cable. In the last few years, such a failure has become very common among providers from Belarus. If you are not using a wireless connection, this problem can only occur if you changed something in the Internet settings yourself. Or as a consequence of the system being affected by a virus or other malicious software. Then first of all check the activity of your firewall and the activity of your antivirus. Have both programs been disabled for a long time without your knowledge? A reason to worry about your network security. Often the problem occurs with a factory modem that the user decided to configure himself. Missing several points in the instructions or inconsistently performing moves leads to the appearance of such an unpleasant notification.

DNS server is not responding, how to fix it?

What can we do without having access to the network:

  1. Reboot the modem. The simplest and effective method, just reboot the device. Helps with eliminating most minor troubles if a problem arose during use. After a reboot, the equipment returns to the original parameters that were at the time of startup.
  2. Check if the DNS address is specified correctly in the settings. To do this, we will need “Internet Protocol v4”, which can be found in the properties of “Local Area Connections”. You can find out the required address from your provider; it must be indicated in the documents issued to you.
  3. Update the drivers for the network card. This manipulation helps solve the problem if the previous driver did not work correctly.
  4. Check your antivirus and firewall settings again. Some systems block network access via wireless networks or specific IPs. Go to settings and make sure everything is in order.

Device or resource DNS server is not responding

All these methods are designed to assume that the provider does not have any problems, and the problem lies in your lost settings or a faulty network card. But sometimes things may be different. Due to overload or purely technical problems, the operator does not have enough capacity, and some of its DNS servers do not work. No amount of “dancing with a tambourine” will help you in such a situation, because the problem was not created by you.

In this case, there are two generally accepted solutions. If you do not have an urgent need to gain access in the next few minutes, simply notify the operator about the current situation and demand the fastest possible solution. But you understand perfectly well that any malfunction requires a certain time to eliminate it. The servers will start working in a few hours, your time will be wasted. If deadlines are running out, important work has not been completed, or you urgently need to contact someone, the proposed option is not suitable. If you have a DNS client service running, you can use Google's DNS. Most often, the user makes a mistake by changing the server settings to connect using a network cable, leaving the data for the same wireless connections. If you are afraid of confusion, change the parameters in both fields; this will not reduce the performance of your laptop or computer.

What if it's not a fault?

Public access points and workplaces often block access to certain resources. The list of “undesirable” sites includes:

  1. Social media.
  2. Online cinemas.
  3. Torrents.
  4. Resources with prohibited content.

In this case, you can also correct the situation in two ways. Either talk to the network administrator and ask to remove the restriction, or use anonymity tools. Most of the restrictions help you bypass proxy servers. Dozens of websites and browser extensions are now available, thanks to which even a beginner can understand the issue. More advanced users can use the TOR or i2p browser. For visiting social networks these last two options will not work.

When the DNS server does not respond, not all experienced network users know what to do. It is enough to call the provider at the main office and ask him to quickly resolve the problem. Even if she is on your side, the employees will explain what needs to be done and in what order.

What to do if the DNS server is unavailable

The problem when the DNS server does not respond persistently haunts users of the Russian segment of the global network. Although you can easily get rid of most of the difficulties that arise simply by reconfiguring the DNS for the proper functioning of the Internet on the user’s computer.

If the DNS server is unavailable, and all the user’s devices are in good condition and there are no financial debts to the provider, then, as a rule, there is no access to world wide web due to incorrect settings. You just need to know how to correct errors in the settings and there will be no difficulties with Internet access.

Below is detailed guide To fix the problem, you just need to strictly follow all the sequential steps of the instructions.

What are DNS servers used for?

What is it and why are DNS servers needed? When going to any site on the Internet, a certain directory on the server becomes available to the user. This section stores information that the user's computer's Internet browser reproduces in the form of a familiar web page. All servers have an individual “IP”, through which login is carried out.

The main requirement for DNS is that they provide accurate redirection from the “IP address” to domains that no longer have a digital address, but an alphabetic one. For example, the Internet resource “nastrojkin.ru” has a domain name of “nastrojkin” and a zone of “.ru”. On the World Wide Web, this site has an IP - 46.36.219.125. The DNS service, if necessary, gives the user access to nastrojkin.ru with the digital address 46.36.219.125, because machines can only understand numeric codes, not alphabetic ones. However, sometimes it happens that the servers do not work correctly and then an unpleasant message is displayed on the user’s monitor: “The DNS server is not responding.”

A yellow triangle with “!” appears on the Set panel. inside.

Instructions for troubleshooting

The following sequential steps must be performed:


When the above service is running, but there is still no Internet access, you need to take the following steps:


If there is no access to the Internet after carefully following the above steps, most likely there are errors directly in Windows work. You can use the well-known function of rolling back the OS to a time when everything worked fine. To this end, you only need to take a few steps:

  1. Through “Start” open the “System Restore” window;
  2. Select a restore point and roll back the system.
  3. Restart PC.

Most common difficulties

Often, such difficulties arise when users entered network settings incorrectly or because the computer was infected with malicious applications. Therefore, it is recommended to make sure that the anti-virus databases of the installed utility are up to date and that the firewall is active.

Sometimes problems appear due to incorrectly entered parameters in the interface of your router or banal omissions of some items in its settings.

192.168.1.1

Beginner users of high-speed Internet access, due to their lack of any experience with computer networks, periodically encounter various problems that a more experienced user or IT specialist would solve “one or two”. One of these common problems is the error: DNS server is not responding. The most interesting thing is that Internet access itself usually works fine, Skype and ICQ also work, but the pages in the browser do not open. What to do?

Let's first figure it out - what kind of server is this and what is it for?!

What is DNS, how does it work?!

As you already know, site names in the global page are made in in letter form so that they can be easily read and subsequently easily remembered. But the computer network itself (both local and Internet) is built on digital IP addresses. That is, behind a beautiful symbolic name there is a set of numbers hidden.

So, DNS (from the English Domain Name System) is a complex step-by-step hierarchical system that stores all the information about the symbolic names of nodes on the Internet and quickly allows you to convert an address from one type to another. For example, you want to go to the website privet.ru and enter it in the browser. Your computer sends the DNS server a request like:

"What is the IP address of the site privet.ru?"

DNS checks information against its database or contacts higher-level servers. The resulting result will be like this:

"The site privet.ru has an IP address of 190.16.99.134"

It is sent back to the computer that sent the request. Thus, if the DNS server does not respond or there are some problems with it, then the user will not be able to open any site or page. And yes, Internet access itself will work great, like all programs that access hosts directly via IP. But the browser will not open the page. If the DNS server does not respond, then Google browser Chrome (and all others on this platform) will display an error: net err name not resolved. Example:

That is, the browser cannot perform the resolv operation - that is, it cannot convert a letter address into a digital one and displays the message "Name not resolved".

Let's look at what options there may be to solve the DNS problem.

If the DNS server does not respond, change it!

Each more or less large provider has its own DNS servers. And all network settings are made in such a way that when a subscriber connects, he automatically receives everything he needs to work. Including the addresses of the necessary servers. But not everyone can boast of a stable job. Some telecom operators generally leave their DNS at the “as is” level, without paying due attention to it. But in the end, it works very poorly, problems constantly arise with it and it crashes, causing users to receive errors like “The DNS server is not responding.” The use of public servers from the largest IT companies in the world will help solve the problem. I prefer to use Google public servers:

Or from Yandex:

77.88.8.8 77.88.8.1

How to register them in Windows 10?! Very simple! Click the Start button and open Operating System Settings. We need the "Network and Internet" section:

In the menu on the left, you need to select the type of connection through which you access the Internet, and on the right, click on the link “Configure adapter settings.” The Windows Network Connections window should open:

Right-click on the connection icon and select “Properties” from the menu that appears. The following window will open:

Here you need to find and double-click on the line “IP version 4 (TCP/IPv4)” to open the Internet Protocol properties window:

Here you need to check the “Use the following DNS server addresses” checkbox at the bottom of the window. After this, two fields below will become available, in which you need to enter DNS IP addresses. Above you see an example with Google servers, and below - from Yandex:

After that, click on the OK button to apply the changes. Now we launch the browser again. The "err name not resolved" error should be resolved.

The antivirus has blocked DNS and it is not responding!

In some cases, the cause of problems with access to the Internet is an overly active antivirus, or rather its network module - Firewall or Firewall. He may not like any request and will easily block access to a particular site on the Internet. Or, as an option, it can block the operation of the Windows DNS client and it will not be able to send or receive requests, which means normal operation The PC on the global web will be paralyzed and the error “DNS server is not responding” will start to appear.

Therefore, when such a picture appears, for diagnostic purposes, it is worth trying to briefly disable the Firewall of the antivirus, as well as the Web Anti-Virus module, if it is present in your security system.

In the case where your Firewall is installed separately, you must also suspend its operation for the duration of the diagnostics.

If after this the problems with the DNS stop and the sites begin to open normally, the reason must be looked for in the firewall rules. By the way, don’t forget to turn it back on, otherwise you risk getting a number of other problems due to malware activity on the network.

Windows DNS client does not work

For how the operating room Windows system contacts the DNS server, a special network module - the DNS client - responds. He is the one responsible for sending and receiving requests for domain names. But sometimes it can start to fail. First you need to restart it. Right-click on the computer icon on the desktop and select the “Manage” menu item:

In the “Computer Management” window that opens, select the “Services” section. On the left will be displayed full list all available Windows 10 system services. Find the DNS client line in it:

We check that the status column has the value “Running”. After that, right-click on the line and select the “DNS client” item. In the menu that appears, select "Restart".

Note: If the client is disabled or suspended for any reason, you must enable it again. To do this, double-click on this line to open the service properties:

We check that the startup type is set to “Automatic”. After that, click on the “Run” button. Checking Internet access.

When all else fails

If, despite all the steps taken above, your pages still cannot open, your browser writes “net err name not resolved,” and Windows throws up the error “DNS server is not responding,” then a global failure of the operating system is most likely to blame. To finally verify this, try connecting another PC, laptop or tablet instead of your computer. If everything works perfectly on it, then only windows recovery. To use it, go to windows settings 10 and select the "Update and Security" section:

Here you need to go to the "Recovery" subsection and find the item "Return the computer to the initial state". Click on the "Start" button and follow the instructions of the wizard. After the procedure is completed, you will receive a working operating system with it completely restored to its original state system files. You can check Internet access.

How to solve DNS server problems

Before you find out why the DNS server is not responding or unavailable, as well as solving other problems with it, it is important to get information about the server itself or refresh your memory if you have dealt with this before. The DNS server is designed to provide information, communication between computers on the network and other similar operations. The abbreviation DNS itself stands for Domain Name System, which means their totality. For clarity, let's look at a small example.


Sometimes there may be problems with the DNS server, but they can be solved if you follow all the instructions

Let's imagine that all computers on the network are people who are assigned a number at birth (for a PC on the network this is an IP address). For even greater understanding, we will assume that the address in question belongs to some site. So, so that people don’t get confused with numbers, they give each other names. In our case, this will be the name of the site, that is, what you type in address bar browser. But people understand names, but machines need numbers, which is why IP addresses exist. Thus, to ensure this work of exchange between alphabetic and digital data, they came up with domain system names, which stores in its memory the correspondence between IP addresses and site names. If you access www.google.ru, for example, and the DNS server at your Internet provider has fallen, then you will not go to the site, but will see an error warning. Now, if we understand a little about the essence of this service, we can move on to solving the problem.

Can't find address

What to do if you can’t find the DNS server address? This problem is also very common, but there can be many reasons for its occurrence. Therefore, we will consider the most popular:

  1. First, be sure to check the operation of your router (that is, there may be a problem with the connection you are using). You can reboot your Wi-Fi router or wired modem, and then try accessing the site again.
  2. Secondly, you may experience a failure on the provider side, then you should contact them directly. This will significantly save your time and nerves.
  3. The browser used to access the Internet is also important, which may also be the reason why it is not possible to convert DNS address server. Try using a different program or application.
  4. If problems occur only on one of your devices, then you should definitely correct its settings. First, you can try to check whether the client service itself is running. Launch Control Panel on your computer or laptop. Open the “Administration” item, where, in turn, launch “Services”. In the “General” tab, check the following parameters: startup type should be automatic, status “Running”. If it is turned off, then click the “Run” button in the same window.
  5. If you cannot find the server address on only one or two sites, then it is likely that the error lies in the site itself. Then it will be enough to wait some time until the work is restored. It's also worth trying out on multiple devices. If the problem occurs at all, then we turn to the second point above.
  6. If the methods described above do not help, try using the Microsoft FixIt utility, which can be downloaded for free from the official website (http://support.microsoft.com/kb/299357/ru). It can also help if you are unable to resolve the server's DNS address.

DNS server is not responding

So what should you do if your DNS server isn't responding? Now we will solve this unpleasant problem. Please note that this solution is also suitable if the server's DNS address cannot be resolved. We will look at several ways to eliminate this problem, since, unfortunately, there is no single “life preserver”.

Switch to DNS from Google

  1. First, you will need to clarify the question: is the DNS client running on your device (computer or laptop)? To do this, write “Run” in the “Start” search bar and run the found utility. In the field of the window that appears, enter services.msc. Now, in the list of services that appears, find the client we need. If it has an automatic startup option and operating status, then move on to the next point. Otherwise, set these items according to the specified criteria.
  2. Next, you will need to switch to public domain name systems from search giant Google. The only thing you should pay attention to is that when working with some providers, redirection to a page with a notification about the end of funds in your personal account may not work. But if this is not a critical problem for you, and the correct operation of the server is more important to you, then we will describe to you how to do this.
  3. Launch Network and Sharing Center in your computer's Control Panel. Open the “Change adapter settings” tab, where you need to select the one from which your Internet works. If you have both a wired and wireless connection, then configure both adapters just in case to avoid conflict situations.
  4. Right-click on it and in properties select “Internet Protocol Version 4”, where we will also need properties.
  5. In the "General" tab, enter the following parameters:
  • The preferred DNS server will be 8.8.8.8
  • The alternative will be the following: 8.8.4.4
  1. Click OK and close all settings. Check if the problem is resolved. Usually, in most cases, switching to Google's DNS helps when the DNS server does not respond or the server's DNS address cannot be resolved. Therefore, we hope that everything was resolved successfully for you too.

  1. Network problems. You need to check that the server has an active allowed connection: check the client’s hardware settings, as well as their serviceability. Make sure you can communicate with other devices or modems that are on the same network as the DNS server. To do this, you can easily use the ping command.
  2. If the previous solution did not help, then you need to perform an additional check. Using the nslookup command, check the ability of your server to respond to clients themselves if the DNS server does not respond.
  3. It happens that the browser writes that it cannot find the address. It is possible that the IP address you are interested in simply needs to be added to the list of restricted interfaces for the server (addresses allowed for servicing). This solution will help those users who had a setting on the server to limit the IP addresses that need a response.
  4. Be sure to check your computer for viruses or malicious codes using a special antivirus utility. Very often, computer or network problems arise due to viruses on your PC or laptop. Therefore, do not omit this item under any circumstances and conduct a deep scan and, if necessary, clean up of infected files.

Conclusion

Dear friends, today we learned how to solve several problems, namely, what to do if: the DNS server does not respond or is unavailable, you cannot find the DNS server address or convert the DNS server address. We hope that you were able to resolve this issue and it no longer torments you with its presence. Please note that most methods are suitable in almost all cases, so try using universal solutions first and then specific solutions.

If you see a DNS error while using your computer or the Internet, remember that there is a problem with the settings. If this problem is not resolved, the user will not be able to visit the desired website.

What is DNS?

For a domain, DNS will be the name of the service and will help in gaining access to resources on the Internet. The goal is to translate the address the user enters into the browser. Translation is carried out from the language used into the computer language. This procedure helps the computer read and understand the address to allow access to the site passing through the server.

What is a DNS error?

Error of this type for a particular website is mainly due to the lack of an active connection to the network. It also means that the equipment is not able to connect to the Internet to convert the entered address. For this reason, the computer is not able to visit the selected site.

Errors occur for certain reasons, and most often they can be easily resolved. Sometimes the device shows them only for certain resources. In this case, the address may be entered incorrectly or there may be no record of it on the network.

What should you pay attention to first?

If the server is not found due to a DNS lookup error, there may be no problem with your computer. For this reason, you should pay attention to the recommendations presented and use them.

  • It is worth checking whether difficulties arise when trying to access one site or all. In the first case, the resource may undergo some changes or encounter operational problems. The user should wait or use the ipconfig /flushdns command as an administrator in a special line.
  • If possible, you should check: the DNS error appears on one device used or on others as well. If all devices are affected, then the problem may be with the provider. In this case, you should wait until the problem is resolved.
  • When connecting with using Wi-Fi The router must be completely turned off and restarted. The next time you try to access the site, the DNS server error will likely go away.
  • When connecting to the Internet without using a Wi-Fi router, it is recommended to go to the list of connections on your computer. Next you need to turn off the local network and turn it on again.

It is worth understanding that after these manipulations the DNS error may remain. In such a situation, it is worth using other methods to correct it.

Using Google Public DNS

  • You need to go to the list of device connections. An easy way to do this is to press the Win+R key combination and enter the command ncpa.cpl.
  • It is worth choosing the connection used to access the Internet. He is high speed connection PPPoE, L2TP or the local network. The required element is selected and the “Properties” item is clicked.
  • The TCP/IPv4 protocol is selected among the components used by the connection.
  • If the server is not found due to a DNS lookup error, it is important to check what settings are available in the DNS server settings. Upon receipt of an address in automatic mode It’s worth moving on to entering addresses. Then the values ​​8.8.8.8 and 8.8.4.4 are specified. Otherwise, you must first set it to receive automatically.
  • After saving the settings, you should run the command line as an administrator and run ipconfig /flushdns.

Troubleshooting browser problems

Checking DNS connections is possible when using a different browser. To do this, download any web browser. On this moment There are a large number of them, and they are mostly provided free of charge. After the browser is open, you need to connect to the Internet. If the service is not found again due to a DNS lookup error, then there are no errors in the browser. This means there is a problem with other computer settings.

If there are no difficulties at all, the user should troubleshoot the old browser. Quite often they arise due to proxy settings. Accordingly, it is necessary to change them.

Cleaning and changing DNS

First of all, if a DNS error appears, you should clear the cache manually, since the setting becomes outdated over time. This can be done from the command line. This procedure is simple, but it may not be effective. If the DNS connection error persists, you should change the service.

The user has the ability to independently enter an alternative DNS server to make a connection. To do this, go to the ncpa.cpl section and select the active connection, and then go to Properties. You need to find the TCP/IPv4 network protocol entry, which is located in the “Network” tab. Then properties and the option to go to the server address are selected. In the Preferred DNS server field, the user must enter 208.67.222.222. Then in the Alternate DNS server field you need to enter 208.67.220.220. Newly created DNS servers will be open source.

Slow server response when using Google

In this case, the error means that Googlebot is not able to contact him. This happens because it is not working or there is a problem with DNS routing for the user's domain. Most warnings and errors do not affect the functioning of the robot. Their occurrence can also be explained by a long reaction, which is an unpleasant moment for users.

The first thing you should do is make sure that Google is crawling your site. To do this, you should use the tool for the main page of the resource. Google will have access to the site if the user returns the content without defects. The DNS service may be provided by your web hosting provider or another company. It is worth contacting it if the DNS probe finished or other error code appears.

The server can be configured for a site using wildcards so that it starts responding to requests for subdomains. This approach will be successful if the content of the resource can be created by users, and at the same time for each personal page a separate domain is provided. It's worth noting that in some situations this can result in hosts with different names. In most cases, this prevents the resource from being crawled by Googlebot.

Running for viruses

The previously discussed methods may not help. If the DNS error still appears on the screen, and it is not caused by factors that affect the computer externally, then you should scan it for viruses. The user may already have an antivirus installed on their device. It is recommended to use Kaspersky, and its free version will do. trial version. Bitdefender in a similar design would also be an excellent option.

The level of detection and the ability to effectively eliminate viruses, while restoring system parameters, are quite high in these antiviruses than in their analogues. In this case, it is worth using a full system scan. Application this method can be really useful if you can't get rid of the problem in the browser itself.

Antivirus malfunction

It is worth paying attention to the fact that the antivirus itself in some cases can cause problems with connecting to the Internet. This can also be fixed. To carry out the procedure, “ Safe mode" In this case, the computer will restart, during which only the files necessary for the operating system will be loaded. This will help determine whether the problem is caused by an antivirus or another program. To verify this, it is recommended to do the following:

  • First of all, you should turn off your antivirus. If there are no connection errors, you should uninstall the antivirus and install a new one.
  • Next, you need to reboot the device. While loading it, hold down the F8 key.
  • You should select “Safe Mode with Networking” from the options provided.
  • The connection is then checked. If you successfully connect to the network, you can conclude that the problem lies in the program that is currently running on the computer.

It is necessary to carefully study the startup files and disable programs until the faulty one is found.

Router

If the server is not found due to a DNS lookup error, it's worth looking at the router again. Rebooting it may not help in this case. In some situations, settings become damaged. The most correct and quick solution is to reset the device to default settings. As a result, the parameters will be reset wireless network. Along with them, the information transmitted through the port will disappear.

To complete the procedure, you must press and hold the Reset button, which is located on the back panel of the device. In this case, you may need a pointed object, such as a paper clip. Then you need to reconfigure the router. After resetting the device, you should change the wireless network settings, if used by the user. This will reset all Accounts and administrator passwords. Making the settings is a simple procedure, but it requires care and correct actions. If the problem was in the router, then after the work done it should be completely resolved.

Additionally, there is a possibility that the router is completely faulty. If you can't reset it and reinstall it, you should contact your Internet provider. In this case, it will be possible to determine the cause of the difficulty connecting to the network. In addition, the procedure will be performed by a specialist.

The need to indicate the DNS of your hosting in the domain record

A name server is designed to assist in finding information about a specific site. By completing a record in their domain, the user will provide the Internet audience with information in the right direction that will lead to the right place.

If you leave the previous provider's data in the domain record, the user will be transferred to a server that no longer has the site. In this case, it will be impossible to access the site, since the provider has deleted the resource record from the DNS. Correct execution is quite important, and failure to follow the recommendations can lead to difficulties.

You should follow the steps described in the material if the server is not found due to a DNS error. The tips presented will be useful, because they help determine the cause of the problem and eliminate it in a timely manner. The information indicated above will become relevant for Internet users, since many of them are faced with the described difficulty. In addition, you can turn to specialists if you yourself cannot get rid of the problem that has arisen with gaining access to sites. This will be the most correct solution in this case.
