Infrequently, of course, but sometimes usersattempts to access Internet sites are faced with the fact that the browser installed on the system displays a message stating that the DNS server is not responding. Not every user knows what to do to eliminate the problem, but in the meantime there are several simple solutions that will be discussed later.
First, a little theory.What is a DNS server? In fact, it is a kind of interpreter, which makes it possible to convert the numeric addresses of Internet resources into letter designations of domain names.
This saves the user from complicated procedures.memorizing and entering the address of the resource in numerical terms. This is too uncomfortable. Many people know that today the address is entered in the line, consisting of letters, numbers and other characters with the addition of a domain belonging, which looks much easier in practice.
Now let's look at some problems, when for some reason the DNS server is not responding. What to do to troubleshoot will become clear if you look at the causes of failures.
As a rule, among all that may becomethe cause of failures is called provider problems, incorrect TCP / IP parameters, the effects of viruses, spontaneous changes in parameters from specific software, and so on.
The first thing to do when suchproblems, check DNS client activity. To do this, use the services section, access to which can be done by entering the services.msc command in the Run menu (Win + R).
Here you need to find the line with the DNS clientand look at the type of launch used. The value should be set to automatic. If something else is set, the parameter will have to be changed by right-clicking on the menu where the property string is selected.
But this is still not all that can fixsituation if the DNS server is not responding. What to do when a message appears? It is necessary to check the correctness of TCP / IPv4 parameters (this protocol is used most often). To do this, you will need to enter the network properties section from the network management section. Then call the window for changing adapter properties, specify the connection you need and use the connection properties where you need to find the appropriate protocol.
When calling its properties should look atset parameters. In most cases, the provider provides automatic value assignment services, but sometimes they need to be manually entered. In the strings of a preferred and alternate DNS server, you just need to enter the correct values and save the changes to the configuration.
However, after this the problem may not disappear.In particular, this concerns the provider Rostelecom, which gives its own parameters for configuration. But they may not work, and the system will again issue a warning that the DNS server is not responding. What to do in this case? Use a different (alternative) configuration.
For example, you can rebuild access withDNS servers google services. For this, the following parameters need to be entered in the properties of the above protocol: for the preferred one — two digits 8 and two digits 4, for the alternative — four digits 8. There is nothing wrong with changing the values for the alternate and preferred server.
Finally, if this option does not work,You can do a full reset and update the configuration. To do this, use the command line run at the administrator level, in which the command ipconfig / flushdns is first written, then ipconfig / registerdns, then ipconfig / release, and finally ipconfig / renew. After entering each line, press the Enter key.
It remains to add that at least one ofThe above proposed solutions will eliminate the problems with the DNS settings. However, it did not address issues related to viral exposure or to the fact that some types of software that require constant access to the network may spontaneously change the configuration (for example, during a permanent check of licenses). Here it is necessary to apply completely different methods.
