The DNS server is a very essential component when you utilize online services from an ISP (Internet Service Provider). The Domain Name System (DNS) is basically a directory that maintains internet records in its database. So, with the help of the DNS server, it becomes easy for the users to remember the name of a website instead of its corresponding IP address. However, at certain times, you can come across the problem of non-responding DNS server as well. Especially, those who are using Windows 10, are facing DNS issues after applying the system upgrades. So, if the DNS server isn’t responding somehow, it will prevent the users from accessing the necessary websites. Also, you can experience many other technical issues while connecting to the internet.

Fortunately, there are technical solutions to resolve DNS server error and restore the Internet Settings. But, before knowing the fixes and making the server work again, you must know the underlying causes of getting DNS error. Hence, go through this article to know the possible reasons behind the problems in the DNS server. Also, check out the instructions to reset the server and troubleshoot DNS errors.

What do you Mean by DNS Error?

When you experience DNS error, it means your device can’t communicate with the server due to some technical issues. Even if you try to run the Windows Troubleshooter, you might observe that the server is still not responding. However, when you get this error, it generates an error message regarding DNS server. So, according to this notification, your PC or laptop may seem to be configured correctly.

But, there can be internal issues in the server causing this DNS error. When this issue occurs, the domain name will not even work on any of the web browsers on your computer. Basically, you will not be able to open any IP address or access sites due to a defective DNS server. Now, to understand the type of error, you need to have a look at the causes of DNS error.

Why DNS Server Stops Responding on your Device and Causes this Error?

Usually, there are multiple reasons why the DNS server can generate an error. So, let’s discuss those causes of DNS errors that are experienced by most online users.

Down Network

When you come across DNS server problems, one of the most common causes is a dead network. Sometimes, a server can stop working or become down for hours due to various reasons. This is when it will not be able to transmit any single piece of information to the next web server.

If you go in depth of this issue, the reason behind this network error can be as simple as incorrect connectivity of cords. Hence, the server will not be able to relay any information through such defective network cables and cause this error.

DLL Problem

In most DNS server issues, any problem in the Dynamic Link Library (DLL) can also trigger connectivity error. Usually, this problem can occur when the initial DLL files are overwritten by any additional system component on DNS. Otherwise, any latest Windows update can also disable the DLL Settings on your web pages.

Virus or Malware

While visiting sites on a regular basis, users are prone to get affected by DNS server error. However, in most cases, you can come across this issue if there are malware or virus attacks on those websites. According to many web server experts, hackers nowadays are creating malware along with JavaScript.

Hence, many online users can fall into their traps by clicking on these malicious links. In case, your device lacks a powerful antivirus, it can corrupt the system and generate DNS error.
