DNS-error what does it mean?

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

What is DNS?

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

What is a DNS error?

An error of this type for a particular web site basically consists in the absence of an active connection to the network. It also means that the equipment is not available to connect to the Internet in order to convert the entered address. For this reason, the computer is not able to visit the selected site.

Obtaining errors occurs for certain reasons, and most often they can be easily eliminated. Sometimes the device shows them only for certain resources. In this case, the address can be entered incorrectly or there is no entry about it in the network.

What should I look for first?

If the server is not found because of a DNS lookup error, there may not be a problem with the computer. For this reason, attention should be paid to the recommendations presented and to use them.

  • It's worth checking if there is a problem when trying to access one site or everything. In the first case, the resource can undergo some changes or face problems in its work. The user should wait or clear the DNS cache using the command ipconfig / flushdns on the special line as administrator.
  • If possible, you should check: The DNS error appears on one device used or on others as well. If all the devices are exposed to it, then the problem may be with the provider. In this case, you should wait until the problem is fixed.
  • When making a connection using a Wi-Fi router, it must be completely turned off and restarted. The next time you try to access the site, the DNS server error is likely to disappear.
  • When connecting to the Internet without using a Wi-Fi-router, it is recommended to go to the list of connections on the computer. Next, you need to disable the local network and re-enable it.

It should be understood that after the manipulations, the DNS error may remain. In this situation, you should use other methods to correct it.

Using Google Public DNS

It is recommended to use the following instruction if the error is not fixed:

  • You must go to the list of device connections. An easy way to do this is to press the Win + R key combination and enter the command ncpa.cpl.
  • It is worth choosing the connection used to gain access to the Internet. It is a high-speed connection PPPoE, L2TP or local network. The required item is selected and the "Properties" item is clicked.
  • Selects the TCP / IPv4 protocol among the components used by the connection.
  • If the server is not found because of a DNS lookup error, it is important to check what settings are available in the DNS server settings. When the address is received in automatic mode, it is necessary to proceed to the introduction of addresses. Then the values and are specified. Otherwise, you must first set the automatic receipt.
  • After saving the settings, run the command line as an administrator and run ipconfig / flushdns.

Next, make an attempt to go to the site and make sure that there is no DNS server error.

Troubleshoot browser issues

You can check for DNS connections when using a different browser. To do this, you must download any web browser. At the moment there are a lot of them, and mostly they are provided on a free basis. After the browser is open, you need to connect to the Internet. If the service is not found again due to a DNS lookup error, then there are no errors in the browser. This means that there is a problem with other computer settings.

In the absence of any difficulties, the user should conduct troubleshooting in the old browser. Quite often they arise because of the proxy settings. Accordingly, it is necessary to change them.

Cleaning and changing DNS

First of all, if there is a DNS error, it is worthwhile to clean the cache manually, since the configuration becomes obsolete with time. This can be done from the command line. This procedure is simple, but it can be ineffective. If the DNS connection error is not resolved, you should change the service.

The user is able to independently enter an alternative DNS server to make the connection. To do this, go to the ncpa.cpl section and select the active connection, and then go to Properties. You must find the TCP / IPv4 network protocol entry that is located in the Network tab. Then you select the properties and the transition option to the server address. In the Preferred DNS server field, the user must enter Then, in the Alternate DNS server field, enter Newly created DNS-servers will have open source code.

Server slow response when using Google

In this case , the DNS server lookup error means that Googlebot can not communicate with it. This is because it does not work, or there are problems with DNS routing for the user's domain. Most of the warnings and errors do not affect the functioning of the robot. Their occurrence can also be explained by a long reaction, which is an unpleasant moment for users.

Initially, make sure that Google scans the site. To do this, use the tool for the main resource page. Google will have access to the site in the event that the user returns the content without defects. The DNS service can be provided by a web hosting provider or another company. It should be addressed if there is a DNS probe finish error code or others.

You can configure the server for a site using wildcards so that it starts responding to subdomain requests. This approach will be successful if the content of the resource can be created by users, and a separate domain for each personal page is provided. It is worth noting that in some situations this can lead to duplication of content on hosts with different names. This in most cases becomes an obstacle to crawling the resource using Googlebot.

Performing a computer scan for viruses

The methods considered earlier may not help. If the DNS error still appears on the screen, and it is not caused by factors that externally affect the computer, you should perform its virus scan. The user on the device can already be installed antivirus. It is recommended to use the Kaspersky program, and its free trial version is suitable. Also an excellent option will be Bitdefender in a similar version.

The detection level and the ability to effectively eliminate viruses while restoring the system parameters are quite high in these antiviruses, rather than from their counterparts. It is worthwhile to use a full system check. The use of this method can be really useful if you can not get rid of the problem in the browser itself.

Antivirus Trouble

In this case, it is worth paying attention to the fact that the antivirus itself can in some cases cause problems with connecting to the Internet. This is also a real fix. To carry out the procedure, "Safe Mode" is applied. In this case, the computer restarts, in which only the files necessary for the operating system will be downloaded. This will help determine if the antivirus or other program is causing the problem. To verify this, we recommend the following:

  • The first thing to do is to turn off the antivirus. If there are no errors during the connection, remove the antivirus and install a new one.
  • Next, you need to reboot the device. At the time of its loading, hold down the F8 key.
  • Choose "Safe mode with network support" among the suggested options.
  • Then, the connection check is checked. If you successfully connect to the network, you can conclude that the problem is in the program that is currently running on the computer.

You should carefully examine the startup files and disconnect the programs until the defective one is found.


If the server is not found because of a DNS lookup error, it's worthwhile to re-engage the router. Its reboot in this case may not help. In some situations, the settings are corrupted. The most correct and quick solution is to reset the device for the default installation. This will reset the wireless network settings. With them, the information that passes through the port will disappear.

To perform the procedure, you must press and hold the Reset button located on the back of the device. In this case, you may need a pointed object, for example, a paper clip. Then you need to reconfigure the router. After resetting the device, you need to change the wireless network settings if it is being used by the user. This will reset all administrator accounts and passwords. Performing the settings is a simple procedure, but it requires care and correctness of the actions. If the problem was in the router, then after the work it must be completely solved.

In addition, there is a possibility that the router is completely faulty. If you are not going to reset its settings and reinstall it, you should contact your ISP. In this case, you will be able to determine the reason for the difficulty of connecting to the network. In addition, the procedure will be performed by a specialist.

The need to specify the DNS of your hosting in a domain record

The name server is designed to help you find information about a particular site. When completing an entry in your domain, the user will inform the Internet audience of the correct direction that will lead to the desired location.

If you leave the data of the previous provider in the domain record, the user will go to a server that does not already have a site. At the same time, you will not be able to access the site, because the provider has deleted the entry about the resource with DNS. Correctness of implementation is important enough, and non-observance of recommendations can lead to difficulties.

You should perform the actions described in the material if the server is not found because of a DNS error. The presented councils will be useful, because they help identify the cause of the problem and promptly eliminate it. The information mentioned above will become relevant for Internet users, since many of them face the described difficulty. In addition, you can turn to specialists, if you can not get rid of the problem with accessing the sites with your own hands. This will be the most correct decision in this case.
