The majority of the day is spent on the internet, whether it’s for business or for pleasure. To buy an item from an e-commerce website, send a business email, or connect with pals on social media, you may need to connect to the internet.

What does ‘DNS Server Unavailable’ mean?

Your web browser’s domain names are stored on a DNS (Domain Name System) server. As a result, your further visits to the website will load more quickly. Searching for a website/domain name is sent to a DNS server via your router, which then converts it to the IP address. Domain names and hostnames are easy for us to recognize and recall, but computers depend on the IP address instead. A quick and easy way to find the website’s network.

The DNS server may not be available for a variety of reasons, resulting in the ‘DNS Server Unavailable’ error message being shown. In rare situations, the error may be caused by the server, but mostly, it may be solved. Numerous antivirus programs running at the same time might produce a clash, leading to the error.

Having identified the issue and its likely causes, let’s guide you through the different solutions available to solve it!

Need To Restart The Router

A router restart is believed to treat a wide range of internet connection issues. After unplugging it, wait a few minutes and then plug it back in again to restart the router. Upon restarting the router, check to see whether the problem has been resolved.

Flushing your DNS

Flushing the DNS cache can help fix damaged queries. As the primary cause of the issue, this should be the second remedy you try.

  • Search for ‘Windows Terminal’ in the Search Bar, right-click on the appropriate search result, and choose ‘Run as administrator’ from the menu bar.
  • By default, when you run Terminal, the Windows PowerShell tab will be displayed if you haven’t chosen ‘Command Prompt’ as the default profile.
  • In order to enter the Command Prompt, tap on “Command Prompt” from the menu that appears when you hit on the carrot arrow symbol. Instead, you may start Command Prompt by pressing CTRL + SHIFT + 2.
  • You may run the following command by typing it on the Command Prompt and pressing ENTER.

ipconfig /flushdns

  • Then, you should type the following command and hit ENTER.

ipconfig /release

  • In the end, input the following command and press ENTER.

ipconfig /renew

You may now shut off the Command Prompt window and restart the computer. Upon restarting the machine, check to see whether you can connect to the web. If not, continue on to the next step of the process.

Configure the DNS server via Manual Process

By default, your machine receives DNS server addresses from the Internet. It’s possible to manually change your DNS server address to Google’s server if your existing DNS server address isn’t working properly. Many people have reported success with this patch.

  • You need to hit WINDOWS+R in order to open the Run command. You have to input ncpa.cpl in the text field and click on ‘OK’ at the bottom, or press ENTER to access the Network Connections window to manually change DNS servers.
  • Select ‘Properties’ from the menu bar by right-clicking on the network adapter in use.
  • Choose ‘Internet Protocol Version 4 (TCP/IPv4)’ in the properties panel and hit ‘Properties’.
  • Choose Use the following DNS server addresses from the IPv4 attributes, and then add the following data in it.

8 . 8 . 8 . 8 in the field of Preferred DNS Server.

8 . 8 . 4 . 4 in the field of Alternate DNS Server.

  • Now, save the setting of this DNS Server by hitting the OK button.

Then, try to see whether you can access the internet. If not, continue on to the next step in the process.

Eliminate DNS Server Addresses

  • After selecting “Internet Protocol Version 4 (TCP/IPv4)”, press on “Settings” to delete DNS server addresses from the network properties.
  • Chose ‘Advanced’ under ‘Properties’ in the box that appears.
  • Under Advanced TCP/IP Settings, click on the “DNS Server Addresses, in Order of Use” tab “Remove”.
  • Perform this action for all the values in this section and tap Ok to save the modifications.
  • You can eliminate the DNS server addresses for ‘Internet Protocol Version 6 (TCP/IPv6)’ using the same procedure.

Disable Your Antivirus Software

Having antiviruses may appear to be a smart way to improve protection, but there’s a lot more going on in the behind. Several antiviruses may clash with one another, resulting in the DNS server problem on Windows 11. As a result, you should only maintain one antivirus and remove the others.

  • To remove an antivirus, press WINDOWS + R to open the Run command, type ‘appwiz.cpl’ in the message body, and then click OK or ENTER to open the ‘Program and Features’ panel.
  • Find and pick the antivirus you wish to deactivate, then choose the ‘Uninstall’ button at the top.
  • Similarly, delete all antivirus software apart from the one you continue to hold and reset your machine. Check if the problem has been addressed and you can connect to the internet when the machine has restarted.

Run the Troubleshooter for Internet Connections

Windows has built-in troubleshooters that can identify and solve problems with your machine. They’re useful for a variety of situations, including the DNS server problem.

  • To start the troubleshooter, pick ‘Settings’ from the list of choices after clicking the Start icon in the Taskbar or pressing WINDOWS + X to open the Quick Access menu.
  • Choose the right-hand ‘Troubleshoot’ button in the ‘System’ section of Settings.
  • Then, under ‘Other troubleshooters,’ click to see and execute the other troubleshooters that are accessible.
  • Find the ‘Internet Connections’ troubleshooter and select the ‘Run’ box.
  • To finish the troubleshooting procedure, follow the directions and select the appropriate decision when requested.
