Often, of course, but sometimes when users try to access Internet sites faced with the fact that the browser installed in the system displays a message indicating that the DNS server is not responding. What to do to correct the problem, do not know each user, meanwhile, there are a few simple solutions, which further will be discussed.
First, a little theory. What is the DNS server? In fact, it is a shell that gives you the ability to convert numeric addresses to Internet resources for letter designations of domain names.
This avoids the complicated procedure of remembering and entering the address of a resource on a numeric expression. It's too uncomfortable. Many know that the row address is entered, consisting of letters, digits, and other characters with the addition of the domain that looks like in practice a lot easier.
Now look at some problems, when for some reason the DNS server is not responding. What to do for Troubleshooting, it will be clear if you look at the causes of failures.
As a rule, things that can cause problems are called problems from the provider incorrectly configured the TCP/IP settings, exposure to viruses, accidental settings change on the part of specific software, etc.
The First thing to do when you see these problems is to check the activity of the DNS client. To do this, use the services section, access to which can be made by entering the command services.msc in the menu “Run” (Win + R).

Here you should find a line that specifies the DNS client and look at the type of startup. The value must be set to automatic. If set to something else, the parameter will have to change by calling the right click menu, where the selected string properties.
But that's not all that can remedy the situation, if the DNS server is not responding. What to do when prompted? You need to check the settings of TCP/IPv4 (the Protocol used most frequently). This will need to be logged in section of the network properties section of the network management. Then call window change adapter properties, specify the desired connection and use the connection properties, where the need to find appropriate Protocol.
When calling its properties should take a look at your settings. In most cases, ISP provides automatic assignment of values, but sometimes they need to register manually. In the lines of the preferred and alternate DNS servers you just need to enter the correct values and save the configuration changes.
However, the problem may not disappear. In particular, it concerns the provider “Rostelecom”, which gives to configure their own settings. But they may not work, and the system again will issue a warning that DNS server is not responding. What to do in this case? To use a different (alternative) configuration.
For Example, to rebuild the access, you can specify DNS servers with Google services. In the properties of the above Protocol in rows values of servers, you must enter the following settings: preferred – two digits 8 and two digits to 4, for an alternative – four of the number 8. There is nothing wrong in the fact that values for the alternative and preferred server to swap.
Finally, if this option fails, you can do a full reset and update the configuration. To do this, use the command line, running on administrator level, in which first prescribed the ipconfig /flushdns, then ipconfig /registerdns, then - ipconfig /release, and finally ipconfig /renew. After typing each line press the Enter key.
It Remains to add that at least one of the above-proposed solutions would eliminate the problems with the DNS settings. However, it did not address issues related to viral exposure or that some types of SOFTWARE requires constant network access, can spontaneously change the configuration (for example, if permanent license verification). It will require completely different methods.
