Lack of dns server what to do. DNS server is not responding. What to do? The simplest solutions and advice. Checking DNS Service Status

Sometimes users need to independently install and configure a DNS server on operating system Windows 7. It can be used for work purposes, to create your own website, or for any other reason. Windows 7 is a graphical operating system (unlike Linux) whose interface is intuitive, and setting up a DNS server will not be difficult even for a person who does not have special skills. Similarly, you can fix errors with your own hands when the DNS is not responding, unavailable, or not detected.

What is a DNS server and why is it needed

DNS is nothing but Domain Name System. As the name suggests, it is a server that issues domain names to IP addresses on the Internet. All sites have their own IP, in other words, a set of numbers that allows the computer to get to Internet resources (for example, 192.168.11.231). But when the provider changes, the address changes, so how do users know where their web portal is now? This is what a DNS server is for, it gives human-readable names instead of IP and allows you to reach the desired address without knowing the set of numbers.

So, at one point you decided that you need a domain name for your mail, personal website or FTP server. You will need to install and configure a DNS server so that your host can be found without the complicated memorization of a set of numbers.

Where to find and how to enable DNS on Windows 7

The user under whose name all the following operations will be performed must have administrator rights on the computer.

In the Start menu, the first thing you need to do is go to the Control Panel.
If the control panel has a reduced view, then in the “Network and Internet” item, pay attention to “View network status and tasks”. If you have all the control panel items displayed by default in a single list, use the "Network and Control Center and public access».
In the "View active networks" section, find the connection thanks to which you have access to the Internet (the one after "Connection") and click on it.
A new window will open in front of you, which displays all the settings for the selected connection. Click the Properties button.
Among the checked components used by the connection, find "Internet Protocol Version 4 (TCP/IPv4)" or "Internet Protocol Version 6 (TCP/IPv6)" and click the "Properties" button.
Activate the item "Use the following DNS server addresses" and type in the text field the address of your server and an additional one if the first one is inactive.
After that, do not forget to click "OK" to save your changes.

When it becomes necessary to change

Usually everyone uses the DNS server of their provider, but it does not always provide good speed downloads. In addition, such mechanisms often cannot cope with the load and “fall”, thereby limiting your access during worldwide network. Such free services, like Yandex.DNS or Google Public DNS will help get around this problem.

These are two largest companies who can afford high-quality equipment and cope even with heavy loads. Their servers are located in different parts of our country and the world. Thanks to this, as well as to the smart distribution of requests, the signal goes to the nearest available server and the pages on the Internet are loaded several times faster than the provider. In addition, such services have many other settings: filtering, parental control, built-in antivirus and custom blacklist.

In connection with the introduction of new laws in Russian Federation providers are required to block access to certain sites. Many people already know ways to bypass this limitation, and one of them is a DNS server. The law did not affect companies providing DNS connection services, which means that they have another advantage over providers.

How to set up or change

At one of the stages, you entered the server address and an alternative one. This is necessary because domain names from all over the world cannot be stored in one place. When the computer searches DNS for the requested name, it bypasses several servers in order, which you can specify yourself in the "DNS server addresses in order of use" text box. There can be not only two sets of numbers entered initially, but also several additional ones.

DNS suffixes are needed to form internal networks, subdomain names (for example, subdomain.domain.com). If you only need the server to connect to the Internet, you can skip this setting and leave it as the default. If you use, for example, the internal working network, enter the suffixes of its subdomains in the corresponding field.

The enabled setting "Register the address of this connection in DNS" means that your computer will be registered on the server with its address and the name of the device specified in the settings. You can find out what the name of your device is in the "Control Panel" in the "System" item. The enabled item "Use the connection's DNS suffix when registering in DNS" will append an additional suffix to the name of your computer on the network.

In what cases DNS may not respond and what should be done

DNS service is disabled

Maybe the DNS on your device just isn't working. You need to check the settings of system services, for this:

In the Start menu, find "Control Panel".
Select System and Security.
In the next window, click on "Administration".
You will see a list of all available programs, select "Services".
Find "DNS Client" and double click on it.
Pay attention to the "Startup type" - this item must have the "Automatic" setting.
Don't forget to save after changing by clicking OK.

DNS server failure

If all the necessary services are enabled, and the DNS server still does not respond, then it is faulty. In this case, it is recommended to change it. To do this, you need to follow the same steps as when connecting the server, but instead of the old address, enter a new one.

What is a DHCP server and how is it different from DNS

When setting up a DNS server, you often came across the abbreviation DHCP. What is it and what is it for?

DHCP stands for Dynamic Host Configuration Protocol. This network protocol, which automatically gives computers on the network the necessary IP addresses and other settings. For example, a network administrator can specify a range that hosts should be in. This greatly speeds up the setup of a large computer network and avoids many errors.

Unlike DNS, this protocol only deals with IP addresses and their settings. Together, these services are a very powerful service and greatly facilitate the work of system administrators.

A DNS server is needed to store the domain names of various IP addresses on the Internet. Its use has many advantages: faster loading, flexible settings, bypassing resource blocking. Set it up in the operating room Windows system 7 is not difficult at all. And almost any connection problem is solved by turning on the service or changing the server.

The DNS server is not responding - a common difficulty that many users experience. We will teach you how to get rid of this problem in the blink of an eye accessible ways– you will find them in our review! Bookmark it for helpful tips were always at hand.

Reasons for the error

What does “DNS server not responding” mean - this message often appears after network diagnostics. Difficulties are also signaled by an icon in the form exclamation mark that appears on the taskbar.

It is necessary to highlight the reasons why the DNS server is not responding:

Error on the part of the service provider;
There was a failure of the computer settings;
The problem lies in the router.

Failures in the work of the DNS, which is responsible for redirecting an IP address to a domain, is a very common difficulty. But you can get rid of it!

The error “DNS server is not responding” should not scare you - after all, there is a whole range of measures that will help solve the problems found. We recommend that you start with a few simple steps - often they will help you figure out what to do if the DNS server is not responding.

If the Internet is connected via a router via a cable or using WiFi, it is worth turning off the power of the equipment for one or two minutes, and then turning it back on;
Try restarting your computer or laptop in a standard way through the start menu;
Check if the Internet works on other devices - on a tablet or smartphone;
You can try connecting the internet cable to the PC directly.

As you can see, even if the DNS server does not respond, there is a solution! If simple ways did not help, we proceed to complex manipulations. Do not be afraid, every user can handle it.

Client verification

The Internet does not work, the DNS server does not respond, what should I do? No need to wonder - it's time to act. It is worth checking if the service is enabled. To do this, you need to follow a few simple steps:

Use the key combination Win + R, held down at the same time;
A window will appear "Run", in which you need to enter the command services.msc;
Then click on the button "OK";

In the list that appears, find the line with the signature "DNS client";
Right-click and select the line "Properties";
Open the tab "General" and go to the section "Startup type";
Select a value from the list "Automatically";
Click on the "Run" button and then on the "OK" icon.

If the service has been disabled, this method should help - we recommend that you restart your computer. We figured out how to fix the error DNS server does not respond by turning on the service - let's discuss other options for solving the problem.

Clearing the cache

If the DNS server is not responding to Windows, you can clear the cached data.

On Windows 7|8

First, consider the algorithm for 7/8 versions of the operating system:

Run command line on behalf of the administrator;
To do this, click on the "Start" button;
Select the section "All programs";
Go to the line "Standard";
Right click and select an option "On behalf of the administrator" on the inscription "Command line";

Enter several commands in turn;
Reboot your device.

Here are the commands you need:

ipconfig /flushdns;

ipconfig /registerdns;

ipconfig /renew;

ipconfig /release;

On Windows 10

Now let's see how to solve the problem on the tenth Windows:

Click on the "Start" button;
Go to the "Options" icon;

Choose a section "Network and Internet";

Go to the tab "Status";
Find the line "Network reset";

Click on the icon "Reset Now" and confirm the action.

That's all, it turned out to clear the cache. If the DNS server device or resource is not responding, let's play with the settings.

Change settings in connection properties

Are you facing DNS server not responding on Windows 10, 8 or 7? It doesn't matter - you can "kill" the error with a few simple steps.

Click on the connection button on the taskbar with the right mouse button;
Choose a section "Network and Internet Settings";

Open the Wi-Fi or Ethernet block;
Go to line "Network and Sharing Center";

A menu will appear on the left side of the screen - select the item "Change adapter settings";

Right-click on the desired connection and select the line "Properties";

In the "Network" tab, find the line "IP version 4 (TCP/IPv4)";
Select it and click on the "Properties" icon again, it is located just below;

In the "General" tab, find the line "Use the following DNS server addresses";
In field "Preferred" write down the value 8.8.8.8 ;
In field "Alternative" set the value to 8.8.4.4. ;
Click "OK" and reboot your device.

As a rule, it is these actions that help to figure out if the DNS server does not respond to Windows 7, 8, 10. Consider alternative options?

Router settings

This is a fairly rare case, but it is worth considering all the possibilities.

Open any browser;
Enter the IP address shown on reverse side equipment;

Enter the password and login for authorization in the control panel;
Enter the section "Internet" or "WAN";
Certain values are prescribed in the connection settings - compare them with the data in the provider agreement;
If the settings do not match, make the desired changes and save them.

Another easy option to fix "DNS Server Not Responding" is firewall and antivirus management. Often these applications come into conflict with other utilities, and users encounter difficulties.

Disable antivirus for a while;
Or update the version of the antivirus;
Temporarily turn off the firewall.

You should also contact your ISP. If none of the above methods helped, do not rule out technical difficulties on the side of the service provider:

Call support;
Name the contract number;
Voice the errors and wait for a response from a specialist.

Now you know what “DNS server is not responding” means and you can deal with the error yourself. It is not so difficult, it should not scare you - you are armed with the right tools to deal with technical problems!

Today I have prepared an article for you that will help you solve one fairly common error that baffles even fairly advanced users: dns server not responding.

In this article, I will talk about the causes of this error, as well as several ways to solve it. From you in the comments, I will wait for confirmation of what exactly helped you, as well as new options, if someone knows. Go!

1. What does "DNS server not responding" mean?

To proceed to troubleshooting, you need to understand what it means the DNS server is not responding.

To understand the essence of the problem, you should know what a DNS server is. When accessing any virtual page on the network, the user gets access to a specific section of the remote server. This section contains and stores files that are converted by the browser used and offered to users in the form of a page with text, images and other information familiar to the visual perception of any user. Each server has an individual IP address, which is required to gain access. DNS server is a functional tool for comfortable and correct redirection of queries to a domain from a specific IP address.

Often the DNS server does not respond in Windows 7 / 10 when connected to the network via a modem and without using a network cable, as well as for users who use a different wireless Internet connection method. In some cases the error may occur after installing the antivirus.

Important! It is not uncommon for users to personally take an interest and make changes to the modem settings that lead to a loss of communication and an unwanted error. Therefore, it is not recommended to edit working settings without the need.

2. Dns server is not responding - how to fix it?

If the user observes an error, then there are four ways to eliminate it:

. Very often it is enough to reboot the modem to fix the error. During the reboot process, the device returns to its original initial settings and parameters, which helps to quickly and efficiently solve the problem;

Checking the correctness of entering addresses in the settings. To check the literacy and correctness of filling in the DNS address, you need to go to the properties tab "Connections by local network”, there you need to find “Internet Protocol v4” and check the specified address. The information to be entered in this field must be included in the connection contract documents. The server address can also be obtained from the provider by contacting him by phone or in another way;

Update network card drivers. The problem can be solved by changing the provider and in some other situations;

Configuring antivirus and firewall. Modern programs that are designed to protect data and information on a PC from viruses and fraudulent activities can block access to the network. It is necessary to carefully review the settings of such programs.

In order to correct the error with a greater probability, it is necessary to consider specific situations in detail. This is what we will do below.

2.1. On Windows

It is possible to identify several possible solutions problems listed in the table.

Way	Procedure
	It is recommended to unplug the device or use the power off button, if provided in the configuration, and wait for about 15 seconds. After the time has elapsed, you must turn on the device again.
Using the command line	You should call the command line from the administrator of the PC. To do this, click on "Start", then find and click on "Search programs and files" and write cmd. After these steps, a program shortcut will appear. Right click on it computer mouse and select "Run as administrator".Then you should type and execute certain commands, after entering each command, you must press the enter key: ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew
Checking settings and options	You need to visit the control panel and find the "Network Control Center ...". This subsection contains information about the network. You should select the connection you are using, then right-click on the computer mouse and select "Properties". The user will open a new window in which you need to select in turn: Protocol (TCP/IPv6); Protocol (TCP/IPv4). Then you need to click on "Properties". You should check the boxes next to the items: get the DNS server and IP address automatically. When checking the settings, you must be very careful and take into account the information specified in the contract with the provider, if any. This method helps only if there is no specific address specified by the provider.

You can register the addresses provided by Google, which, in the opinion of search engine, help speed up the loading of web pages: 8.8.8.8 or 8.8.4.4.

3. DNS server not responding: TP-link router

Most modern users use TP-link routers and devices. Error DNS server not responding can be eliminated in several ways:

Attention! Some, especially inexpensive TP-link models parameters are lost. In this case, you should follow the setup instructions that came with the device and enter the data and DNS addresses specified in the contract and provided by the provider.

It is better to set the basic settings on the TP-link router, unless otherwise specified in the contract with the provider.

4. DNS server is not responding (Beeline or Rostelecom)

All of the above methods of eliminating the error are designed to ensure that the problems arose from the user. But practice shows that in most cases, problems occur with the provider due to a number of reasons, such as technical malfunctions.

For this reason, it is necessary not to rush when an error occurs, but to wait a while: you can reboot the computer and router during this period without touching any settings. If the situation has not changed, it is recommended to contact the representatives of the provider company and tell about the problem, informing the specialist of the data that he requires: contract number, last name, IP address or other information. If a problem occurs with an Internet connection service provider, he will report this and tell you the approximate time frame for fixing the problem. This is especially true for Internet owners from Rostelecom (I myself am one of those, so I know what I'm talking about). Very useful numbers:

8 800 302 08 00 - technical support by Rostelecom for individuals;
8 800 302 08 10 - technical support by Rostelecom for legal entities.

If the problem does not arise at the provider, then the company's specialist can in some cases help the user solve it by giving competent advice or recommendations.

Novice 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 in one or two. One of these common problems is the error: DNS server not responding.
The most interesting thing is that Internet access itself usually works fine, Skype and ICQ also work, but pages in the browser do not open. What to do?

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

What is DNS, how does it work?!

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

So here DNS(from English. Domain Name System- The Domain Name System) is a complex stepped hierarchical system that stores all information about the symbolic names of nodes on the Internet and quickly allows you to translate an address from one type to another. For example, you want to visit the site private.ru and enter it in the browser. Your computer sends a query like this to the DNS server:

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

DNS checks information against its database or accesses higher servers. The 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, the user will not be able to open any site or page. And yes, Internet access itself will work great, as all programs that access nodes directly via IP. But the browser will not open the page.
If the DNS server does not respond, then in the browser Google Chrome(and all others on this platform) this will display an error: net err name not resolved. Example:

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

Let's look at what options can be for solving the problem with DNS.

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 connected, the subscriber automatically receives everything necessary for work. Including the addresses of the required servers. But not everyone can boast of stable work. Some telecom operators generally leave their DNS at the "to be" level, without paying due attention to it. But in the end, it works very badly, it constantly has problems and it crashes, causing users to get errors like "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 public Google 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, select the type of connection through which you access the Internet, and on the right, click on the link "Configure adapter settings". A window should open Network connections Windows":

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 box "Use the following DNS server addresses" at the bottom of the window. After that, the two fields below will become available, in which you need to register the IP addresses of the DNS. Above you see an example with Google servers, and below - from Yandex:

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

Antivirus blocked DNS and it is not responding!

In some cases, the cause of Internet access problems is too much active antivirus, or rather network module- Firewall or Firewall. He may not like any request and he will easily block access to a particular site on the Internet. Or, alternatively, it can block the work of the Windows DNS client and it will not be able to send or receive requests, which means normal work The PC on the global web will be paralyzed and the error "DNS server is not responding" will start popping up.

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

In the case when you have Firewall installed separately, you must also suspend its operation for the duration of the diagnostics.

If after that the problems with the DNS stop and the sites start to open normally, the reason must be sought in the rules firewall. By the way, do not forget to turn it back on, otherwise you risk getting a number of problems due to malware activity on the network.

Windows DNS client not working

For how the operating room Windows system contacts with the DNS server is answered by a special network module - the DNS client. It is he who is responsible for sending and receiving requests for domain names. But sometimes it can start to fail. The first thing to do is restart it. We click on the computer icon on the desktop with the right mouse button 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 systemic Windows services 10. We find the line DNS client in it:

We check that in the status column it 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 properties of the service:

Check that the startup type is set to "Automatic". After that, click on the "Start" button. Checking Internet access.

When nothing helped

If, despite all the steps above, you still do not open pages, the browser writes "net err name not resolved", and Windows throws out the error "DNS server is not responding", then the global failure of the operating system is most likely to blame. To finally make sure of 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 "Reset your computer to its original state." 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.

The error "DNS server is not responding" can indicate both problems with the 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 complicated is solved quite simply.

Here is 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 possible that some parameters of the operating system do not allow it to connect to the Internet. Therefore, it is better to restart it.
Reboot your router. The same applies - some parameters go astray from time to time. You can try to find them and set them up in the right way, or you can just restart the system. The second option is faster. Just unplug the router from the outlet and turn it on after a minute.
If the Internet does not get through the router, but directly through the cable, check its integrity. If possible, it is even better to go up to the roof of the house to see what is there with the wire - often, for example, hooligans cut them for some reason. If there is damage somewhere, this area is best replaced or isolated.
If you do connect through a router, try connecting directly. That way you can figure out what the real problem is. If the connection is restored with a 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 possible that the provider is doing some work, or for another reason, the connection is temporarily unavailable. Then you just have to wait a bit.

Server settings

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

It is done like this:

Click on the connection icon in the tray (bottom right) with the right mouse button. From the drop down menu select " Network Control Center...».
In the window that opens, click " Change settings…' on the panel on the left.

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)". Click the "Properties" button a little lower.

To put it simply, there should not be any addresses in the next window. Check two boxes " Receive an address automatically", Click" OK", Restart your computer and try to connect again.

If the installation automatic receipt addresses did not help, try setting the addresses of Google servers - and 8.8.4.4.

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

Clearing the cache

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

It, like any other type of cache, should be disposed of.

The same applies to various temporal network parameters.

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

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

They should be entered into the console, which is launched by typing cmd commands to the command window.

Recall 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 drivers helps. network card.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 multiple devices. It is better to follow the steps below for each of them.
Right-click on the device and select " Update drivers».

In the update window, first select the automatic driver search. If the necessary files are found, install them. And if all else fails, try to find 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 that. But the Internet can recover even after a normal update.

Disabling assistive programs

On the computer, certain programs that work with the Internet can be installed.

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

For example, many antiviruses have a parental control feature.

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

Of course, in order to perform such a function, you must have access to the connection.

Another example is the firewall. It literally filters all the materials that get to 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 messed up.

Therefore, all programs that are somehow connected with 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 tray icon and select " Exit" or " Shutdown». 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 disable 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».

Put two checkboxes next to the items " Disable Windows Firewall (not recommended)". Click "OK".

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

System rollback

Most likely one of recent changes in the operating system resulted in no connectivity.

Therefore, it is best to roll back the system to a state where everything was still good.

To accomplish this task, do the following:

In the Start menu, enter the query "recovery". You will be able to find the program System Restore". Run her.
In the first window, click " Next".

Next you will see the available restore points. Rely on the date when everything was fine with the connection. Click on the desired option and click Next.
