One of the most common errors related to the internet connection in Windows is the “DNS server is not responding”, resulting in loss of access to the Internet. The connection icon will most likely have a yellow triangle, and in the browser, when you try to open the site, you will most likely see the error “Can not find DNS address”, “error name not resolved”, or something similar. In this article, we will try to explain the possible reasons behind this issue and some feasible solution that can be enforced to resolve this problem.
What is a DNS Server?
In the world of computer networking, every system is designated by a specified series of numbers called “IP Address”. These addresses are quite long and difficult to memorize for each system. Hence, in order to simplify the overall communication between systems and operator, networking engineers developed “DNS” (Domain Name System). The function of a DNS is to resolve domain names to numbers. To be specific, it resolves domain names into IP addresses. A DNS system basically works like a phonebook where the IP addresses of thousands of domains are stored alongside their unique IP addresses so that when a user enters a domain name, the DNS server will look for the domain name in the stored database and will automatically redirect you to the corresponding website via the IP address.
What is DNS Server Not Responding
This problem is caused by the failure of the DNS server, which is responsible for the redirected IP addresses to the domain. If we talk about the causes of this error, the culprit can be either the computer itself or the router, or the equipment on the provider side. Most of the time, the problem is caused by some misconfiguration on the ISP’s (Internet Service Provider) side. In such cases, there’s not much a user can do to resolve this problem rather than waiting for the ISP service to repair the issue on their own. But, in many cases, it has been observed that this problem may arise due to the presence of meager aberration on the user’s side. in such an event, there are are some proven solutions which can be applied to resolve the problem.

- Once done, Click on “OK” to save the changes. Close the window and restart the system for successful completion.
4: Reset DNS to the Default Value
