DNS service does not answer what to do. DNS lookup error: what is it and how to fix it? In other cases

Access to the Internet is now available in almost every home. Providers must meet consumer requirements and provide stable connection. And when the connection breaks and the Internet disappears, there is no need to rush to scold the operator; perhaps the breakdown is related to your device or software. A popular error that often pops up is that the DNS server is not responding. There are many possible reasons for this unpleasant situation. But every problem has a simple solution.

No connection to the DNS server: what does this mean?

In such an unpleasant situation, access to Internet resources is closed. This message will appear when you try to load any browser, and an exclamation mark will appear on the Internet access icon. This parameter is responsible for redirecting the IP identifier to the domain. The error may be caused by your service provider, router, or user's computer. The problem can be tracked through the system Windows diagnostics 7, 8, 10. Pressing right click mouse on the network connections icon.

The cause of the problem may be simple glitches that are easy to fix. Perhaps the list of submitted simple techniques, will help correct the situation:

  • the answer may be hidden in the router or router. Reboot the device by disconnecting it from power for a few minutes. This rule applies to all models of equipment;
  • restart your computer or laptop. It makes no difference whether you are connected via a modem or directly to the cable of the service provider;
  • exclude the router from the connection diagram and connect directly. This will give information about its serviceability;
  • try connecting to Wi-Fi using a different technology to check if your computer is working properly;
  • remember what could lead to problems, logging into the network may not be available after making systemic changes on the computer (installation, downloading applications).

What is DNS and what is it responsible for - video:

Clearing cache

If the methods presented above did not help, then the problem lies deeper. In this case, when the DNS server does not respond, you can clear the network options cache. To do this you will need:


In the operating room Windows system 10, you can use the network settings reset function.

Checking the DNS connection settings

You can view the DNS server settings in properties available networks. To eliminate errors, you can assign automatic retrieval of DNS addresses, and also use servers Google service. In most cases, this method eradicates problems. Run the following algorithm:


Very often in such situations, filling out digital fields with Google servers helps. Enter: 8:8:8:8, 8:8:4;4. If such an error occurs for all devices connected to wireless communication, then you can solve it in the router settings (WAN section) by filling in the same addresses.

Other reasons

In rare cases, breakdowns occur for the following reasons:


Conclusion

If none of the listed methods did not resolve the problem, then most likely the culprit is not the device or resource, but the Internet provider. Typically, Rostelecom, Dom.Ru, MTS companies notify consumers about the technical work And possible failures in the operation of the Internet.

Video step-by-step instruction for troubleshooting DNS server:

Try contacting technical service support from your operator. Qualified specialists will help you with as soon as possible find a solution. You can solve any problem yourself, the main thing is to understand the essence.

Users usually start the troubleshooting process when they detect a yellow exclamation point on the Internet icon. After the procedure, the system may display the message “DNS server is not responding.” What this means and how to deal with it, we will tell you in the article. The solution may be trivial (for example, rebooting the router or changing the browser), in some situations you will have to check the functionality of the DNS service or clear the cache.

What does this error mean?

Most people don't know what a DNS server is and what it's for. Each resource on the Internet has its own IP address, consisting of 4 bytes. But the user is not able to remember the numerical addresses of numerous sites, so domain names (names of sites that you enter into the address bar) were invented. The DNS server serves to associate a domain with an IP address, so that the user gets to the desired resource.

Now that you know what DNS is, you can understand why your computer won't connect to the Internet. Typically, the DNS server is unavailable due to network problems. Problems with the provider may well be the cause of this error. But there may be situations when the source of the problem is your computer. In the following chapters, you will learn what to do if the DNS service is not responding.

Primary actions

If you encounter the DNS server is not responding message, do not panic, because the problem may not be the resource itself, but the device. Recommends doing a series of simple actions, which in most situations solve the problem:

  • Reboot your computer and router. Unplug the router and leave it turned off for a few minutes. Turn on your router and then boot up your computer.
  • Change your browser. If the error appears in your browser window, try a few alternatives.
  • Update network drivers. Outdated driver is common cause the error under discussion. Download the necessary software from the official website of your manufacturer network card.

Contact the provider

After primary actions Contact your ISP to find out why the server is not responding. The provider may require your full name, contract number, model of the router used or other information. If the problem is on the side of the service provider, you do not need to perform any manipulations. It is enough to wait for corrections. Otherwise, proceed to the subsequent paragraphs of the article.

Checking the DNS client service

The DNS client may be disabled on the computer. In this situation, all previous steps will be ineffective. The following instructions will help you check the client’s status and enable it:


Now you know one of the reasons why the DNS server is not responding. Activating the client will clear the error so you can freely use the Internet.

Changing addresses or settings of DNS servers

Client activity does not guarantee full functionality. Incorrectly configured settings may limit access to global network. As a rule, in the settings there is a parameter automatic receipt DNS addresses, but the router may give them incorrectly. You must set the addresses manually. Follow these steps to make the correct setup:

You can also obtain DNS server addresses from your ISP. Now you know how to fix the DNS server not responding error.

Clearing the DNS cache

To speed up access to specific sites, the computer caches information about DNS servers. Information is located in the system Windows section. Often this cache is out of date and therefore leads to incorrect operation system, which becomes the cause of the already known error. The solution to the problem is simple - clear the cache. The procedure is performed using the command line or restarting the appropriate client.

To get in command line possible in the following ways:

  • Windows 10: Right-click Start and then select Command Prompt (Admin).
  • Windows 7/8/8.1. Click Win combination+R, type cmd and press Enter.

On the command line itself, enter the following commands in sequence:

  • ipconfig /flushDNS;
  • ipconfig /registerDNS;
  • ipconfig /release;
  • ipconfig /renew;
  • netsh winsock reset.

After each of them, press Enter. The final step is to restart your computer. Clearing the cache will help solve connection problems when DNS is not responding. Alternative way– restart the client. To do this, enter the list of services (described in detail in the DNS service check paragraph). By clicking on the required line right-click, click "Restart".

If you encounter problems accessing websites, we recommend that you regularly clear your cache.

Setting up a firewall

Windows has its own security features. Their list includes “Windows Firewall” (or in other words, firewall). A firewall can block access to resources that it considers potentially dangerous to your computer. If you are confident in the reliability of the resources you are using, you can disable the firewall on your computer.

Disabling occurs in a few clicks:


Attention! On some systems, the firewall settings will be unavailable, as their powers will be taken over by the antivirus. In this situation, you will have to temporarily disable your antivirus to change the settings. Disabling FireWall in some cases removes the “no access to DNS server” message.

Checking the system for viruses

On Windows 10 and other OS versions, the “DNS server is not responding” message may be caused by malicious software. software. Viruses can completely block access to the network or to individual Internet resources. It is recommended to scan the system with an antivirus or using Live media (for example, a flash drive).

VPN and other programs

To solve the problem when the DNS server does not respond, specialized software will help, which allows you to manually install a server from the list of available ones. Bright representative in this segment – ​​DNS Jumper. The program does not require installation. The application can select a service automatically, but if necessary, the user can manually set the desired server.

Windows is the most popular OS, used by millions and tens of millions of people all over the planet, but this does not save it from many shortcomings. Among them - frequent breakdowns and errors appear on empty space. Surely each of you has encountered “ dns server not responding" after starting the PC with a dead battery motherboard or waking it up from sleep mode. Windows 7 is especially prone to this problem; if you put your computer to sleep even for a short time, you will immediately see this message when you try to return to work. Let's look at the causes of the problem and how to solve it.

DNS server does not respond in Windows 7, 8, 10: how to fix the error

Now it appears that the DNS server is not responding, but how to fix the error? The easiest way is to simply go into the network settings and diagnose it. The computer itself will tell you what the problem is and try to fix it. Then disconnect from the network and restart it, making a short restart. If the DNS servers do not respond to Windows 7, you can simply unplug the cable. If the DNS server does not respond to Windows 10, and the provider does not know anything, then there is no need to look for a problem in the hardware. Try restarting Windows, because the system itself may block the signal.

What to do first

If the DNS server is not responding and you don't know what to do, don't panic. Fixing the error is not difficult if you follow the instructions:

  1. When connecting to the Internet using routers or modems and a similar error appears, restart the device, having previously saved all the settings already made to the maxi network and the DNS address itself. After disconnecting power from the device, wait a minute, then reapply power.
  2. After this, restart your computer, and just in case, go to safe mode. It doesn't matter whether you use a modem or not.
  3. If you connected the Internet using a router and use wireless technologies, check the speed and operation on other devices. There may be a problem with the modem itself.
  4. If you are using a router and you have the opportunity, connect the cable directly to the computer to check whether the problem is software or hardware.
  5. Remember the last time everything functioned normally and what you did before the system started displaying an error.

If none of this helps, you will have to full diagnostics system, follow the instructions below.

Checking the operation of the DNS Client service

When an error appears that the DNS server is not responding, do not rush to change the Internet settings and check whether the service is functioning in principle. To do this, just press Win + R on your keyboard and enter the command services.msc, which manages, as you might guess, all the services of the system. There, find the management service using the query “DNS client” and go to its properties by right-clicking the mouse. Turn on automatic start, then start the service if it was not active before. If the service was turned off, then after a simple reboot of your PC everything will fall into place and you will get rid of the problem at the root.

Changing DNS servers in network card settings

After the procedure described above, if it does not help, you should check whether the DNS server address is set correctly. Go to network management and right-click on necessary connection, then select Properties. There, find the settings and check the path that is specified for the DNS server. If the field is completely empty, contact your provider and clarify whether you need to specify a special IP address, and if so, which one. Then restart the network for the settings to take effect, this should help with the connection. Additionally, you can specify DNS Google servers- this will help if the error is caused by problems with the availability of your provider's DNS.

Clear DNS cache and reset network settings

If you made any changes to the settings, and initially everything worked well, you need to reset the network settings, and to do this, open the command line. Simply enter the cmd command in the application search, right-click on the found file and open it as administrator. In the window that appears you will need to enter following commands(after each command you must press Enter to execute it). After executing all commands, you must restart your computer.

  1. ipconfig /flushdns
  2. ipconfig /registerdns
  3. ipconfig /renew
  4. ipconfig /release

This is how we correct all the DNS settings that you changed and solve the problem if the device or resource DNS server does not respond.

DNS server does not respond: TP-link or another router

Sometimes the error “dns server is not responding” and the problem with wi-fi work may occur due to a router or router such as TP-link. IN in this case You can try these simple steps:

  • Reboot the router
  • Check that the router settings are correct - maybe they are simply wrong
  • Reset the router settings and configure it again using the instructions for the router and the data from the agreement with the provider. If the instructions are lost, no problem. Call your provider's support and they will help you remotely reconfigure your router

DNS server does not respond: Rostelecom or another Internet operator

If the Internet does not work and the DNS server does not respond, the operator, for example, Rostelecom, may be to blame. Call your provider and ask if everything is fine with their Internet, if there are any problems, and if their side of the barricade shows that you are connected. Often, it is the provider that causes most of the problems with errors of this kind.

Conclusion

If the DNS server does not respond, do not panic, the error will be fixed in a matter of minutes, and you will be able to enjoy the Internet again. It is enough to check the settings and, as a last resort, call the provider.

The “DNS server is not responding” error may indicate problems with your computer or 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. Find the real reason This error can be quite difficult to resolve. It is quite possible that some parameters operating system They don't allow her to connect to the Internet. Therefore, it is better to start it again.
  • Reboot your router. The same applies - some parameters go wrong 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 direct connection, 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.

This needs to be entered as "Preferred DNS Server" and " Alternative DNS server" respectively.

Clearing cache

When connecting to DNS, a lot of various information, in other words 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 cmd commands to 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:

  • In 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 better to do the following actions for each of them.
  • Right-click on the device and select " Update drivers».

  • In the update window, first select automatic search drivers. If necessary files will be 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 " Search for drivers on this computer" 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 Internet connection 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, to perform this function, you must have access to the connection.

Another example is a firewall. It literally filters all the 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’s 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”. In the picture below this process shown for .

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:

  • In the window that opens, click " Turn Windows Firewall on or off».

  • Place two checkboxes next to the items “ Disable Windows firewall(Not recommended)" Click "OK".

As you can see, there is nothing complicated about this.

It’s unpleasant to encounter problems with your Internet connection, but sometimes it can’t be avoided. One common failure occurs when it cannot find DNS address server. Let's look at what it is this problem, and how to eliminate it.

Description of the error

DNS (Domain Name System- domain name system) is a bridge between human and computer perception in the sense that it allows you to transform user-friendly alphabetic Domain name(what is written in address bar of the form “www.google.com”) into a machine-friendly numeric equivalent (node ​​IP address).

A DNS error (aka "Error 105", ERR_NAME_NOT_RESOLVED) occurs when the web browser is unable to perform the translation, then the site will not be accessible.

Troubleshooting steps

First of all, you need to find out at what level the failure occurred.

Possible options with signs:

  • problems at the site level— an error is issued when loading only one site, others open;
  • problems at the provider level- not a single device in this local network does not load pages, there is an error everywhere, when connecting the same device to another network, the connection works correctly;
  • router level failure- the signs are the same as in the previous case;
  • computer level error— Internet problems are not detected on other devices connected to the same network.

Solving the problem at the PC level

First of all, make sure that DNS service works and restart it:


Did not help? Next step- cleaning DNS cache .


Changing the DNS server address


Alternative DNS server

If previous actions did not lead to the desired result, you can connect to a different DNS server. In this case, DNS requests will be addressed instead of the provider's server to the one you specify. This method can also be used to bypass restrictions that ISPs may impose on websites.

Please note the following point: changing the DNS server address to one of those located in open access puts your data at risk. For security reasons, use servers with a good reputation, for example, Google Public DNS, OpenDNS, Yandex.DNS.

Setting up Google DNS

Login to " Network connections", select the connection to your network, TCP/IPv4. Check "Use the following DNS server addresses" and enter Google IP addresses: 8.8.8.8 and 8.8.4.4.

The addresses of other servers are written in the same way.

Features of Google Public DNS

When using servers from Google processing request may be slower than when working with local servers providers. The reason for this phenomenon is the remote geographical location, due to which the request needs to travel a greater distance.

To counteract the possible delay, Google uses its own technologies for scanning the Internet and caching information, which benefits performance.

A possible cause of an error when loading a specific site is that it has moved to another IP address while the information on the local DNS server has not yet been updated. Because Google crawls the web constantly, the information on its servers is more up-to-date, and connecting to them may solve the problem.

Antivirus malfunction

Problems with the Internet connection can be caused by a faulty antivirus. To find out if this is your case, put your computer in safe mode.

For Windows 10, switching is done in the following way:


In safe mode, the antivirus software does not turn on; if sites load normally, the antivirus is the source of the problem, you need to reinstall it.

Checking the router

Level problems Wi-Fi router the “symptoms” are no different from a failure at the provider level, but there is a way to distinguish them.

Disconnect the Ethernet cable from the router and plug it into the computer connector.

This will establish an Ethernet connection. If, when connecting directly, the problems with the Internet are resolved, the problem is with the router, and it needs to be rebooted.

To reboot, turn off the router, wait 10-30 seconds and turn it on again.

In other cases

If you have tried all the above methods and the problem still persists (no page loads), contact your ISP.

If one specific site produces an error, the cause of the failure is on the side of its owners or hosting. In this case, you will have to wait. Sometimes it can be informative search query like “why is the site xxx.yyy.com not working”, which may shed light on the source of the problems.
