A description of DNS server functionality

As we have already explained and you are familiar with the functions of the DNS server, the DNS server is a decentralized naming system that is responsible for converting the hostname (alphabetic domain name) to the IP address; in fact, the DNS server plays the role of a translator. The DNS server plays an important role in accessing online websites, without access to the DNS server it is impossible to visit a site because when the user enters the web address in the URL of the browser, the DNS server uses it through the router and then automatically translates it as an IP address (internet protocol addresses).

Why do we encounter the “DNS server not responding” error?

If the DNS server cannot perform its function correctly in the process of separation and mapping hostnames to IP addresses, you will receive the message “DNS server not responding”. This message informs you that DNS is unresponsive to connect to the desired site, or that your browser’s connection to the Internet has encountered a problem.

There are various reasons behind this error, the most common of which is the failure of the DNS server or incorrect configuration of DNS and its records, even it may be related to the old browser or the temporary outage of the DNS server. Misconfiguration of the DNS server, which can be the main cause of this error, is usually caused by the wrong entry of the IP address during the recording process.

In any case, the main cause of this issue is disturbances in network and Internet connections or related to DNS server settings. Of course, other reasons can cause such a problem, which we will mention some of the most common reasons:

  • DNS server failure
  • Temporary unavailability of DNS server due to server outage or a high volume of traffic
  • Old browser
  • Disturbance in network connections
  • Router or modem failure
  • Network and hardware problems
  • Blocking Internet access by updating some antivirus software

As you have noticed, when using Windows VPS and any Windows system, various reasons cause the problem of the DNS server not responding, which is nothing to worry about because this issue is not unsolvable; Troubleshooting network problems can be effective in solving this problem.

Therefore, there are various and simple methods such as updating or changing the browser, changing DNS servers, clearing the DNS server cache, restarting the router or modem, fixing the router problem by changing the Ethernet ports or using different Ethernet cables, and also solving network problems can be useful to solve the problem of DNS server not responding.
