DNS service does not respond to Windows 7. What to do if the DNS server does not respond? DNS server does not respond

DNS (Domain Name System) is a domain name system, which is presented on servers in the form of a specific hierarchy. When working on the network, you can errors in the work of the domains, which will be saved exactly the change in the server used. In Windows 7, it is possible to configure the DNS-seer and change its parameters, which is very simple, just a couple of steps.

DNS destination

Computing devices do not understand our language, like the address that we enter into the search string of the browser used. The computer understands only IP - client code designation (user). Such information is provided to the server in the form of a binary number system, for example, 00100010.111500000.00100000.11111110. This set of numbers is automatically converted into a decimal system, already for our understanding. In this case, with the above example, it will be 255.103.0.68.

For customers, remember even such a set is extremely difficult. Therefore, when registering a domain on the relevant resources, we invent some kind of alphabetic designation.

After registering the domain, we get both the letter expression of the future site, and the numerical, presented in the form of a binary or decimal number system.

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

All computer requests are carried out using DNS

Among other things, this address ensures the security of the user during the surfing on the network. Thus, we are protected from various kinds of malicious software. If this parameter is disabled on the computer, the client will not be able to access one or another network resource.

When you should change the DNS address and where to take it

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

Some servers can be pretty far from hosting. This has a direct impact on the download speed of the site page. It is recommended to use free addresses that you can easily get from many search engines. For many users it will be the best way out of the current situation. Ideal: Yandex.dns or Google Public DNS. In this case, the connection will be carried out 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 our own resources. When the user specifies this information in the site domain, then automatically "says" the entire global Internet community about the location of the resource so that it can be found, open and read the information stored there.

Changing DNS will allow you to access locked sites.

The same addresses from Yandex and Google are not associated with any obligations with Roskomnadzor, in contrast to Internet providers that provide you with the possibility of network operation.

How to know DNS and where it is

As in the case of most system parameters, you can find information about the DNS server through the control panel.

Open the Start menu and select "Control Panel".

Open the "Control Panel" through the "Start" menu

In the window that appears, click the "Network and Internet" tab and click on the "View network status and tasks". Here it will be possible to detect the section "View Active Networks". It will be located all networks to which your computer is connected. Click 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"

After clicking, a window with a variety of parameters will be displayed. You need the "Internet protocol version 4 (TCP / IPv4)". Highlight it with the mouse and open the "Properties".

Highlight "Internet Protocol version 4 (TCP / IPv4)" and click on "Properties"

The window that opens will be the whole information you are interested in. By default, the server's automatic receipt should be enabled.

Automatic Obtaining IP Address is optimal for users' legs

In order to establish a new address, you should re-do the manipulation, which was mentioned above (to get into the Properties of the Internet version 4 (TCP / IPv4)).

You need to change the tick with "Get the DNS server address automatically" to "use the following DNS servers addresses" and enter the desired address.

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

Change similar options should be extremely careful and carefully. In advance, analyze the DNS server and better give up the use of little-known.

Setting up DNS.

Setting and changing the address is carried out in the same way as receiving information about it. At first, you again need to get into the Properties "Internet version 4 (TCP / IPv4)". You can configure and change the DNS server in the "Advanced ..." tab.

In the "Advanced" tab, you can independently change the customer's order to servers.

You should know that all sites and domains are stored on various servers, and their huge amount. Thus, if you specify a specific address, and it is not on the same server, the machine automatically switches to another and so on until the desired result is found.

You can configure DNS suffixes, but without the need to change anything better in this parameter

DNS suffixes are needed exclusively to providers of networks to provide various kinds of access levels, as the address of any site can be separated into several parts.

The countdown of the domain levels is carried out from the end, for example, in the server.domain.com address there are three levels and Server is the third.

Without the need to configure nothing here, since everything must be done for you. You risk the fact that you will have access to most sites at all and everything will have to configure again.

DNS server does not respond: how to fix problems in Windows 7

This is one of the most popular problems with which users may encounter during Internet surfing. By the way, it is not the most pleasant, since the reasons for her appearance can be a lot. Such problems can be solved in several ways.

First of all, it is required to check whether the relevant service is activated on a personal computer.

Open the Control Panel and go to the System and Security section.

In the "Administration" parameter, select "Services".

In the list presented, find the record "DNS client" and double-click on it with the left mouse button.

In the window that appears, change the type of service to "automatically".

If the automatic startup type has already been installed, then the problem is not in your computer, but is on the side of the server used. You can get rid of the fault by changing the address, which is described above.

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

One of the described options must help. If this still has not happened, update the network adapter drivers and check the cable connection to the computer. If it does not help, call your Internet provider.

If the error is represented as incorrect resolution of DNS names, you will also need to change the address.

What is a DHCP server and what it differs from DNS

DNS is part of DHCP, which is a much more advanced system. DHCP is engaged in the organization of the network used, the distribution of IP addresses and the creation of a network ecosystem. It contains the most different information that processes and operates in the future: the IP address of the host, the IP address of the gateway and the reduction of the DNS server. All these parameters are configured by the system in automatic mode, and it is extremely recommended to resort to their change.

DNS are designed to transmit IP addresses, obtaining data on resources and connections to them. If necessary, any user can change the address to speed up the operation of the network, protect your computer from unwanted consequences and optimize the work of sites as a whole. All this is possible through the change in the domain server.

Windows is the most popular OS, which is used by millions and tens of millions of people across the planet, but it does not save it from many flaws. Among them are frequent breakdowns and the appearance of errors in scratch. Surely each of you came across "DNS server does not respond" after running a PC with a discharged battery on a motherboard or out of sleep mode. Especially this problem is sinned by Windows 7, it is worth at least to immerse the computer into a dream at least, and you will immediately see this message when you try to return to work. Let's deal with the cause of the problem and how to solve it.

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

Here you have it out that the DNS server does not respond, but how to fix the error? The easiest all is simply to go to network settings and to diagnose it. The computer himself will give out the problem and will try to fix it. After that, disconnect from the network and start it again by performing a small restart. If the server DNS does not respond to Windows 7, you can simply pull out the cable. If the DNS server does not respond to Windows 10, and the provider does not know anything, then you should notice the problem in the hardware. Try to restart windows, because the system itself can block the signal.

What you need to do first

If the DNS server does not respond, and you do not know what to do, you should not panic. Eliminate the error is not difficult if you follow the instructions:

When connecting the Internet using routers or modems and the appearance of such an error, restart the device, after saving all the settings already entered in the maximum network and the DNS address itself. Disconnecting the power from the device, wait a minute, then again serve the current.
After that restart the computer, and just in case, go in safe mode. It does not matter whether you use the modem or not.
If you have connected the Internet with a router and use wireless technologies, check the speed and operation on other devices. Perhaps problems with the modem itself.
If the router is used and you have the ability to connect the cable directly to the computer to check the breakdown in the software or in the hardware.
Remember when the last time everything functioned normally and what you did before the system began to output the error.

If nothing of this helped, you will have to fully diagnose the system, for this, follow the instructions below.

Checking the work of the DNS client service

When an error jumped out that the DNS server does not respond, do not hurry to change the Internet settings and check whether the service functions in principle. To do this, just press Win + R on the keyboard and drive the command. services.msc.Manager, as easy to guess, all system services. There, find the management service upon request "DNS client" and go to its properties on the right click of the mouse. Enable automatic launch, then run the service if it has not been active before it. If the service was turned off, then, after a simple reboot of your PC, everything will fall into place, and you get rid of the problem on the root.

Changing DNS servers in the network card settings

After the procedure described above, if it does not help, it is worth checking if the server address is called correctly. Go to network management and right-click on the required connection, then select "Properties". There are settings and check the path that is specified for the DNS server. If the field is empty at all, contact the provider and specify whether to specify a special IP address, and if so, what. After that, restart the network so that the settings take effect, it should help with the connection. In addition, you can specify the Google DNS servers - this will help, if the error is caused by the problems with the availability of the DNS of your provider.

Clearing DNS Cache and Reset Network Settings

If you made any changes in the settings, and initially everything worked well - you need to reset the network settings, and to do this, open the command line. Just enter the CMD command in the search by applications, click on the file found right-click and open it on the name of the administrator. In the window that appears, you will need to enter the following commands (after each command, it is necessary to make ENTER for execution). After executing all the commands, you must restart the computer.

ipconfig / Flushdns.

ipconfig / registerdns

ipconfig / renew.

ipconfig / Release

So we correct all the settings of the DNS that you changed, and solve the problem if the device or resource DNS does not respond.

DNS server does not respond: TP-LINK or other router

Sometimes the error "DNS server does not respond" and the problem with work Wi-Fi may occur due to the router or router, for example, TP-LINK. In this case, you can try to perform the following simple actions:

Reload Router

Check the correctness of the router settings - maybe they simply knocked

Reset the router settings and set it up again using the instructions for the router and data from the contract with the provider. If the instruction is lost - not trouble. Call the support of your provider and you will remotely help 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 may be to blame for this, for example, Rostelecom. Call the provider and ask if they have everything well with the Internet, there is no problem and whether the barricades are displayed on it that you are connected. Often it is precisely from the provider most of the problems in errors of this kind.

Output

If the DNS server does not respond, you should not panic, the error is corrected in a matter of minutes, and you will again be able to enjoy the Internet. It is enough to check the settings and, in the extreme case, call the provider.

Rostelecom is known primarily as the largest internet access provider, offering to take advantage of the high data transfer rate and modern technologies. DNS Rostelecom is necessary for study, being an essential component to ensure communication with the data transfer server. Users can be used both their own operator servers and the analogues of the world's largest giants.

In this material, we will consider in detail the following questions:

what is DNS. Without an understanding of the basic principle of operation, the client will not be able to use the capabilities of the operator at full power;
organization of the maximum connection speed and complete list of addresses for manual input;
the differences between the automatic and manual setting of parameters;
possible problems in everyday use. Why an error "does not meet the DNS server" may appear when you try to connect to the World Wide Web.

The functioning of the World Wide Web without using the DNS protocol is not possible, as it is responsible for processing a user request, definition of a domain name and further connection to it. It is using a DNS server to go to a specific site, after entering the query in the search string. Also, using this service, an individual IP is assigned to your device, with which the feedback between the site and the computer becomes available.

The primary setup of the network includes entering the Rostelecom Server DNS parameters to the appropriate fields. This procedure can also be performed automatically. Also, the DNS registry may include a list of prohibited sites to view sites, which includes: viral, fraudulent, pornographic and other projects prohibited by law. So you can secure the PC user from visiting such projects.

Summing up the above, the following factors can be distinguished:

without DNS, you will not be able to access the websites located in the World Wide Web;
the protocol can act as a kind of "filter" from unwanted content;
connection speed, delay between the transfer of data packets and some other technical parameters also depend on the selection of the serving server.

Rostelecom DNS addresses

Having understood with the purpose and importance of choosing a "domain name system", we turn to the review of the servers available to user use. Subscribers of the largest domestic broadband access operator to the Internet connection can take advantage of both own and third-party services. Private users often rarely notice the difference between a variety of addresses, but for specialized use of access to the network, appropriate testing will be required. We will consider this process in detail in the next section.

The operator's IP is as follows:

48.193.36 - acts as a priority;
158.0.6 - can also be used in some regions.

To simplify custom use, the preferred DNS server Rostelecom is selected in automatic mode when connected to an Ethernet network. At the same time, the operator uses predominantly its own resources. If delays in downloading the pages of sites, problems with the loss of data packets and other network problems, the reason can be in the selected domain name system. In this case, it is recommended to go to solutions from other world leaders - Yandex or Google.

What DNS server to register: Rostelecom

If the technical features of the standard DNS server are not enough, you can make an independent diagnostics to detect the most effective address for everyday use. This will help you with additional software "DNS Benchmark", which can be downloaded from the official website of the developer on free conditions.

After installing the installation, you will be prompted to add an IP for testing. It is recommended to enter the following data here:

48.193.36 and 213.158.0.6 - Standard solutions from Rostelecom;
8.4.4 and 8.8.8.8 - options from Google, which acts as a priority DNS host in the opinion of a plurality of priority developers;
88.8.8 and 77.88.8.1 - no less effective servers from Yandex.

Now the program will automatically check the speed and quality of the connection with the central servers, which will allow to obtain information about the most efficient DNS address for everyday use. After that, you will need to manually configure the network connection.

To register the IP address of the DNS server Rostelecom in the Windows operating system as follows:

Open the Start menu and go to the Control Panel section;
Find the "Network Connections" category and open it;
Click on the option "Properties of the Target Connection";
In the window that appears, select IPv4, remove the checkbox from the "Automatic DNS search" item;
Manually enter the most efficient IP address;
Save the changes, proceed to the Internet connection.

So you can provide the most efficient connection to the network.

"DNS server does not respond to Rostelecom" - what to do

Since the functioning of the domain name system directly depends on the technical equipment and correct configuration, there is a possibility of an appropriate error on the screen when trying to use the Internet connection. If the DNS server is not available, Rostelecom proposes independently to re-configure and change the IP. Detailed instructions for this action was considered in the previous section. It is first recommended to make an independent diagnosis of the quality of the compound, which will ensure comfortable conditions when working with the World Wide Web.

Error "Unable to Find DNS Server Address - Perhaps the server is unavailable" It is often found quite often and many users faced it more than once. The reasons for its occurrence may be very different, but first you need to figure it out what kind of error.

First it is worth understanding what DNS is the server address.

The computer works directly with the numbers, and the user picks up the site in the address bar with letters. Specifically to agree on these actions existsDNS servicewhich each domain name (site address) translates into numbers (the IP address of the resource) in order for the computer to understand where to go. Therefore, if for some reason the service does not work, the computer cannot receive the DNS server address and gives an error.

Causes of occurrence

The error "cannot find a DNS address server" is a set of reasons, from incorrectly working service due to a computer failure to a non-working site. Consider all of them in more detail:

the cause of the DNS error may become random operating system failure On a computer or just its incorrect loading. In this case, it is enough just to restart the PC so that everything came to normal;
for problems from the providerwhich provides internet access, some sites may not open. To find out if the provider is fine with the provider simply call in technical support;
also may be problems on the side of the resource When switching to which an error occurs. To make sure about this ask friends to go to the site and if they didn't get anything likely, the site is temporarily unavailable and will soon earn. Roskomnadzor is possible, but these cases are identical;
on the PC can happen service failureDNS. Due to viruses or other reasons. Viruses can also make changes to the Hosts file, thereby causing an error.
antivirus program designed to protect the user's PC by mistake can block access to the resource;
settingsTCP /IP may invoke an error on a par with the router settings;
and the last cause of the occurrence may be all sorts browser extensions.

Error correction

The first thing to do is to restart the PC and check whether other sites open if the problem is present only on one, then most likely there are technical work and after some time it will work.

Check the status of the DNS service

The Windows system is stable, but there are failures in various services. This failure can occur in the DNS services. To restore work it is necessary:

Reset cache

The DNS service is like many others have a cache. It is filled with time and can become a problem for stable Internet operation. Clear it as follows:

Installing alternative DNS.

To correct the error, "Unable to find the DNS server address" can be tried to set alternative DNS server. You can do this by opening " Network connections"Through the" taskbar "or press the Win + R keys and enter there nCPA.cpl:

Problems with antivirus

Antivirus on the PC is called up to protect against various threats from outside, but sometimes there are situations when the antivirus blocks the necessary sites. Check whether the antivirus is guilty to the absence of access to the Internet, you can turn it off for a while. After the antivirus is disabled to open the browser and try log in to the desired resource. If everything goes you can try to reinstall the antivirus or put another.

Router malfunctions

The router has its own settings that can block access to the site for a number of reasons. Easy solution to solve such a problem reset router to factory settings. After that, it should be configured according to the requirements of the provider.

You can reset the settings on the router using the button " Reset.", Which is located on the rear panel of the router. Its necessary clamp Then let go and give the router will reboot. Often, the button is in the recess and for pressing it will have to take advantage of something thin, it is done to accidentally do not reset the settings.

Checking Hosts File

Malicious software can harm the computer by changing the parameters of the HOSTS file. To eliminate malfunction you need to go along the way C: \\ Windows \\ System32 \\ DRIVERS \\ ETC Open HOSTS file by any text editor on behalf of the administrator (the most convenient to use "Notepad") and delete all postswho do not start with the lattice, except 127.0.0.1 localhost. After that, to save changes and check whether the problem disappeared.

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

In such an unpleasant situation, access to Internet resources is closed. Such a message will appear when trying to upload 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 culprit of the error may be a service provider, router or user computer. The problem can be traced through the Windows 7, 8, 10 diagnostics system. By right-clicking on the network connections icon.

The cause of problems may be elementary failures that are easy to fix. Perhaps the list of presented simple techniques will help to correct the position:

the answer may hide in a router or router. Perform a restart of the device by turning it off for a few minutes. This rule applies to all models of technology;
reboot your computer or laptop. Without a difference, you are connected via a modem or directly to the company providing services cable;
exclude a router from the connection scheme, and connect directly. This will give information about its health;
try connecting to Wi-Fi using other techniques to check the maintenance of the computer;
remember what could lead to malfunctions, entering the network, possibly not available after making system changes in the computer (installation, application download).

Cleaning cache

If the methods presented above did not help, it means that the problem is hidden deeper. In this case, when the DNS server does not respond, you can apply the network option cache cleaning. This will require:

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

Check the DNS connection settings

You can see the settings of the DNS server in the properties of available networks. To avoid errors, you can assign automatic receiving DNS addresses, as well as use Google service servers. In most cases, this method eradicates problems. Follow the following algorithm:

Right click on the icon of available connections located on the desktop system panel.
Open the General Access Management Center tab. And go to the adapter settings section.
In the list of available connections, select the active, which is currently running, go to the properties. Wi-Fi is indicated as a wireless network, and the cable connection is Ethernet. In the menu that appears, click TCP / IPv4 and go to properties.
If the DNS address number number is specified, then activate the automatic receipt of addresses by putting a tick in the appropriate place.
Save and restart the system.

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

Other reasons

In rare cases, breakdowns occur for the following reasons:

Conclusion

If none of the listed methods eliminated the problems, most likely, the culprit is not a device or a resource, but the Internet provider. Usually, Rostelecom, Dom.ru, MTS, notify consumers about conducting technical works and possible failures in the Internet.
