Are you facing the DNS server not responding issue on Windows 10? Well, you don’t need a network engineer for that, here’s how to do it with DIY steps.
Are you thinking how to troubleshoot DNS server errors? For troubleshooting this error you need to go to the source of the problem which can be many. Here, in this article we have tried to deal with some fundamental considerations prior to going ahead with troubleshooting DNS server errors. However, you need to know what DNS is and why such errors occur in case the idea is vague.
What is DNS server?
The expanded form for the abbreviation DNS is ‘Domain Name System’. It could be better understood by the following explanation.
Each computer connected to the internet has its own unique IP address. This is actually a number series where a dot separates each number in the series. Similarly all the websites sharing the resources of a web server also have their own unique IP address assigned to them. Thus, for opening a website, instead of typing just the URL, you can type its IP address after ‘http://’ on the Search bar of the web browser. Thus, the function of the DNS server is to resolve IP into domain name.
Why does DNS error occur?
If the server is unable to resolve the IP address you typed into its corresponding domain name, it displays error message. It could be due to the problem of internet connectivity at your end or at web server’s hosting the website.
How to fix the DNS errors?
If the problem is caused due to the internet connectivity problem from your side, you can try some basic troubleshooting steps.
Firstly, you must change the settings of the firewall, which scans the incoming and outgoing internet data to and from your system. Maybe the browser got blocked. For this, either take the help of any expert browser support service provider, or do it manually by configuring the Windows Firewall Settings in the Control Panel.
Your system asks the DNS server for the translation of IP address whenever you try to open a site from the browser. The IP address information is stored in the ‘DNS cache’ of your system. Thus, for quicker browsing, when you try to open the same website next time, the already stored information of DNS is recovered from the cache.
If you have earlier made an attempt at retrieving IP address that failed, it will be stored by your system and it will give rise to DNS error. For troubleshooting this you have to clear the DNS cache, by opening the command prompt and typing 'ipconfig /flushDNS'. After this again reloads the website and the error will be solved.
With these guidelines, the question ‘How to fix DN errors?’ won’t be a big challenge for you. In case of any DNS problem due to firewall, feel free to call Firewall Support.
