Dns does not respond what to do windows 10. How to solve problems with the DNS server. Ways to resolve the error

Sometimes, after rebooting the computer, or even for no obvious reason at all, instead of the main page of your favorite site, the frightening message “DNS server address not found” is displayed (sometimes the message is even more succinct “DNS server error”).

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. Technical work 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 network card connector.

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 the network settings of Windows 7.

2. An unlucky wizard who manually set .

3. DNS settings that are broken after uninstalling any system/network programs or problems with the automatic start of the DNS service.

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 command line terminal again 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 a free utility from Microsoft and instructions for use - https://support.microsoft.com/ru-ru/kb/299357

Very often people leave comments on the site, from which I take topics for new articles. Recently, a comment was left on an error post that said the error "The server's DNS address cannot be found." The Internet disappears, sites stop opening, and an error appears in the browser stating that the DNS address could not be found. After which the Internet stops working, not a single site opens.

There is such a problem, and the error itself about problems with DNS is very popular. The solutions for all versions of Windows will be the same. It doesn't matter if you have Windows 7, 8, or ten. And it doesn’t matter in which browser the error appears, and for which site. I will show Windows 10 as an example. Let's try to resolve the error “This page could not be opened” or “Cannot access the site”. Typically, the main error message depends on the browser you are using.

Cannot find server DNS address: what is it?

Before moving on to the solutions, I want to write a few words about the error itself. DNS is needed to resolve website addresses (which we indicate by letters) to digital addresses. Browsers only understand them. Accordingly, when DNS cannot resolve the address, the browser reports an error that the site cannot be opened and writes that it cannot find the DNS address of the server.

The error itself may look different. It all depends on the browser.

As you can see, in the screenshot above I have an error accessing the site youtube.com. It doesn't matter, the error can happen for any site. For example, for vk.com, facebook.com, google.com, yandex.ua, etc. It all depends on the site you wanted to open.

Determining the cause of the DNS error

There may be several reasons why you encountered this error: your Internet provider, problems with the site, an error on the router, or a failure on your computer. It is not difficult to identify them. Let's go in order:

• The problem is on the site side. If you see the error “The server's DNS address cannot be found” when you try to access only one site, but other sites open normally, then most likely the problem is on the side of a specific site. You can just wait a little, or try opening the site from another device (via another connection). If it opens, then try to solve the problem on your device.
• Error with DNS due to Internet provider or router. If you have many devices, and they all fail to open websites and get the same error, then the problem is most likely on the side of the Internet provider, or in the router. To get started, just turn off the router for a minute, turn it on, and check if the error disappears. If not, then connect the Internet directly to your computer (if possible), and try opening sites. If the error persists, contact your Internet provider support.
• The problem is in the computer (laptop). Most likely it is. In this case, on other devices (if any), everything works fine, the sites open. In this case, try following the tips in this article.

What to do and how to fix the error (using Windows 10 as an example)

Let me remind you that the tips are suitable regardless of what Windows you have installed. I advise you to follow the recommendations in the same order.

Checking the DNS Client service

We need to check if the DNS Client service is running and restart it. To do this, right-click on the "Computer" icon (This PC) and select "Manage". Or press the keyboard shortcut Win+R, and run the command compmgmt.msc.

In the new window, select "Services" and find "DNS Client" in the list. Right-click on the service and select Properties.

Check if the startup status is set to Automatic and click Ok.

Then, right-click on the service again and select "Restart". Restart your computer.

Resetting the DNS cache

If after restarting the service the sites do not open, try resetting the DNS cache. It's very easy to do. Launch Command Prompt. In Windows 10, simply right-click on the Start menu and select “Command Prompt (Admin).” If Windows PowerShell (administrator) is there, launch it. Or we find and launch the command line through the search.

Execute the command ipconfig/flushdns.

Restart your computer and check the result.

Registering an alternative DNS from Google

This method almost always helps. By default, DNS addresses are assigned to us by our Internet service provider. And the problem may lie precisely in them. Therefore, we can register our own static DNS in the properties of our Internet connection on the computer. It's best to use Google's DNS:

They are reliable and work quite quickly. Although, local addresses can process requests faster. But you don’t even have to pay attention to this. A large number of users use DNS addresses from Google. I strongly do not recommend using any other addresses, it can even be dangerous.

Right-click on the Internet connection icon (on the notification panel), and select Network and Sharing Center. Go to the "Change adapter settings" section.

Further attention! Right-click on the connection through which you are connected to the Internet and select "Properties". If your computer is connected via Wi-Fi, then this is a Wireless Network Connection (in Windows 10 - Wireless network). If you just connect via a network cable, then click on “Local Area Connection” (or Ethernet on Windows 10). Also, you may have a high-speed connection, with the name of your provider.

Select the item “IP version 4 (TCP/IPv4)” and click the “Properties” button. Next, put the switch next to “Use the following DNS server addresses” and enter the addresses as shown in the screenshot below.

If the error "Cannot find the server's DNS address" persists, restart your computer and try opening the site again.

1 Try temporarily disabling your antivirus. Perhaps the problem with opening sites appears precisely because of it. Better yet, boot your computer in safe mode and try opening sites in your browser. 2 If the problem occurs on all devices connected to the same router, and changing the DNS helped on one of the devices, then you can change the DNS to addresses from Google in the router settings. Then, all devices will automatically use them. On different routers, this process looks different. These parameters always change on the page with settings for connecting to your provider. On TP-Link it looks like this:

If you have a different router and don’t know how to change, then write the model in the comments, I’ll try to tell you.

3 Reset TCP/IP parameters. Open a command prompt as an administrator, and run the following commands:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart your computer and check if it works.

If you have any questions, ask them in the comments. Don’t forget to share new solutions and write about ways that helped you get rid of the error with looking up DNS addresses when surfing the Internet.

Beginner users of high-speed Internet access, due to their lack of any experience in working with computer networks, periodically encounter various problems that a more experienced user or IT specialist could solve “one or two times.” 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, the names of sites on the global page are written in letters 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 here it is DNS(from English Domain Name System- Domain Name System) is a complex stepwise hierarchical system that stores all information about the symbolic names of nodes on the Internet and quickly allows you to transfer an address from one type to another. For example, you want to visit the site 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 the Google Chrome browser (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:

8.8.8.8
8.8.4.4

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 that the normal operation of the PC on the global web will be paralyzed and the error “DNS server is not responding” will begin to appear.

Therefore, when such a picture appears, for diagnostic purposes, it is worth trying for a short time disable Firewall antivirus, as well as a module Web Antivirus, 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

A special network module, the DNS client, is responsible for how the Windows operating system contacts the DNS server. It is he who is 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. A complete list of all available Windows 10 system services will be displayed on the left. 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".

Comment: 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 restoring Windows will help. To use it, go to Windows 10 Settings and select the "Update and Security" section:

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

DNS (Domain Name System) is a domain name system that is presented on servers in the form of a certain hierarchy. When working on the network, you can encounter errors in the operation of domains, which is why changing the server used will save you. In Windows 7, it is possible to configure the DNS server and change its parameters, which is done very simply, in just a couple of steps.

Purpose of DNS

Computing devices do not understand our language, as well as the address that we enter into the search bar of the browser we use. The computer only understands IP - the code designation of the client (user). Such information is provided to the server in the form of a binary number system, for example, 00100010.11110000.00100000.11111110. This set of numbers is automatically converted to the decimal system, for our understanding. In this case with the example above, it would be 255.103.0.68.

For clients, remembering even such a set is extremely difficult. Therefore, when registering a domain on the appropriate resources, we come up with some kind of letter designation.

After registering a domain, we receive both an alphabetic expression of the future site and a numerical one, presented in the form of a binary or decimal number system.

When a user sends a request to the server (indicates the address in the search bar), it goes to the DNS server - where the site domain is stored. The system automatically searches for matches, and if everything is fine, then we get to the site.

All computer requests are made using DNS

Among other things, this address ensures the user’s security while surfing the Internet. In this way, we protect ourselves from various types of malicious software. If this parameter is disabled on the computer, the client will not be able to access this or that resource on the network.

When should you change your DNS address and where to get it?

By default, the option to automatically obtain a DNS address is enabled on your computer. This setting is optimal for most users. Only in exceptional situations should it be changed. For example, when you need to access a certain resource on which you have been blocked.

Some servers may be located quite far from the hosting. This has a direct impact on the loading speed of website pages. It is recommended to use free addresses, which you can easily obtain from many search engines. For many users, this will be the best way out of this situation. Ideal: Yandex.DNS or Google Public DNS. In this case, the connection will be made through the nearest server.

Yandex.DNS or Google Public DNS services are free to use and very reliable

It is most advisable to change the DNS address for owners of their own resources. When a user sets this information in the site domain, he automatically “tells” the entire global Internet community about the location of the resource so that it can be found, opened and the information stored there can be read.

Changing DNS will allow you to access blocked sites.

The same addresses from Yandex and Google are not bound by any obligations with Roskomnadzor, unlike Internet providers who provide you with the opportunity to operate the network.

How to find out DNS and where it is located

As with most system settings, you can find DNS server information through the Control Panel.

Open the Start menu and select Control Panel.

Open Control Panel from the Start menu

In the window that appears, open the “Network and Internet” tab and click on “View network status and tasks.” Here you will find the “View active networks” section. It will contain all the networks to which your computer is connected. Click on the one that is responsible for connecting to the Internet.

Select the active network that is responsible for connecting to the Internet

Now go to the properties of the selected network. Click on "Properties"

Once clicked, a window with many options will appear. You need "Internet Protocol Version 4 (TCP/IPv4)". Select it with your mouse and open Properties. Highlight “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”

The window that opens will contain all the information you are interested in. By default, automatic retrieval of the server address should be enabled.
Automatically obtaining an IP address is optimal for advanced users

In order to set a new address, you should repeat the manipulations mentioned above (go to the properties “Internet Protocol version 4 (TCP/IPv4)”).

You need to change the checkbox from “Obtain DNS server address automatically” to “Use the following DNS server addresses” and enter the desired address.

Check "Use the following DNS server addresses" and set the DNS address you need

Such options should be changed with extreme caution and care. Analyze DNS servers in advance and avoid using little-known ones.

DNS Settings

Setting up and changing an address is carried out in the same way as obtaining information about it. First, you again need to go to the “Internet Protocol Version 4 (TCP/IPv4)” properties. You can configure and change the DNS server in the “Advanced...” tab.

In the “Advanced” tab, you can independently change the order in which the client accesses the servers

You should know that all sites and domains are stored on different servers, and there are a huge number of them. Thus, if you specify a specific address, and it is not on one server, the machine automatically switches to another, and so on, until the desired result is found.

You can configure DNS suffixes, but unless necessary, it is better not to change anything in this setting

DNS suffixes are needed exclusively by network providers to provide various levels of access, since the address of any site can be divided into several parts.

Domain levels are counted from the end, for example, in the address server.domain.com there are three levels and server is the third.

There is no need to configure anything here, since everything should already be done for you. You run the risk that you will completely lose access to most sites and will have to set everything up again.

DNS server not responding: how to fix problems in Windows 7

This is one of the most popular problems that users may encounter while surfing the Internet. By the way, it is not the most pleasant, since there can be many reasons for its appearance. Such problems can be solved in several ways.

First of all, you need to check whether the corresponding service is activated on your personal computer.

Open Control Panel and go to System and Security.

In the Administration option, select Services.

In the list presented, find the “DNS client” entry and double-click on it with the left mouse button.

In the window that appears, change the service startup type to “Automatic”.

If the automatic startup type has already been set, then the problem is not with your computer, but is on the side of the server you are using. You can get rid of the problem by changing the address, as described above.

It is best to use search engine addresses: the address from Google is 8.8.8.8, and from Yandex - 77.88.8.1.

One of the options described should definitely help. If this still does not happen, update the network adapter drivers and check the cable connection to the computer. If this doesn't help, call your Internet provider.

If the error appears to be incorrect DNS name resolution, you will also need to change the address.

What is a DHCP server and how does it differ from DNS

DNS is part of DHCP, which is a much more advanced system. DHCP deals with the organization of the network used, the distribution of IP addresses and the creation of the network ecosystem. It contains a wide variety of information that it processes and exploits in the future: host IP address, gateway IP address and information about the DNS server. All these parameters are configured by the system automatically, and changing them is highly not recommended.

DNS are designed to transmit IP addresses, obtain data about resources and connect to them. If necessary, any user can change the address to speed up the network, protect their computer from unwanted consequences and optimize the operation of sites in general. All this is possible by changing the domain server.

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 the address bar of your browser. But people understand names, but machines need numbers, which is why IP addresses exist. Thus, to ensure this exchange between alphabetic and digital data, a domain name system was invented, which stores in its memory the correspondence of 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 resolve the DNS server address. 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.

Solving problems for other reasons

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 anti-virus 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.
