Windows 8, Windows 8.1, and Windows 10 users have complained that when they try to access some websites on their browser, such as Google Chrome, they are presented with an error message that says, ‘Server DNS address could not be found.’

If you have encountered this issue on your PC, you may wonder what it means and how to get rid of it.

As you may well know, every website has a domain name and a numerical IP address. The IP (Internet Protocol) address is a series of numbers that represent a website. However, since it is difficult to memorize and enter a URL, the domain name, such as example.com, is used instead as it is more readable and easy to remember. Thus, whether you enter the numerical IP address or the human-readable domain name of a website, you will still arrive at the associated web page.

What DNS servers do is match the domain name of the website you want to visit with its associated IP address. This process happens quickly. However, if the DNS server fails to retrieve the IP address, then you get the error message that is being discussed here.

This problem often occurs in the following scenarios:

  • The domain you are trying to access is down.
  • The DNS server is not accessible.
  • There is an IP address change at the server level, and your local cache is still returning the old IP address.

In this article, we’ll show you how to fix the “Server DNS address could not be found on Windows 11 and Windows 10” error.

How to Fix the “Server DNS Address Could Not Be Found” Error

The error might not prevent you from accessing all websites. Sometimes, it may appear on random pages, so you could still be able to perform searches on Google, but other sites, such as YouTube and Facebook, will fail to load.

The solutions we’ve presented below will help you resolve the issue. However, there is nothing you can do if the problem is due to a server misconfiguration of the web page you are trying to visit.

How to Fix the “Server DNS Address Could Not Be Found” Issue in Windows 10:

  1. Restart Your Router
  2. Run the Network Adapter Troubleshooter
  3. Resolve network adapter driver issues
  4. Clear the host cache in Google Chrome

Afterward, open your Google Chrome browser and see if the error message will still appear when you try visiting a website. The issue will have been resolved. However, if it persists, move on to the next solution.

Fix 7: Delete Files in the ‘ETC’ Folder

The Hosts file is a text-based file (which means that you can make changes to it by using a text editor) that was designed to serve the purpose that DNS servers now serve, i.e. to map IP addresses to their domain names. Another use for the Hosts file is that it speeds up your browsing. If your DNS server is down or not fast enough, you can choose not to rely on it and instead manually enter the domain name and IP address mappings in your Hosts file so that your computer can quickly find the addresses.

The Hosts file is contained in the etc folder on your computer. Some users have reported that deleting the contents of the etc folder helps resolve the ‘Server DNS address not found’ issue. Follow the easy steps below to get it done:

  1. Press the Windows icon button + I button on your keyboard to open File Explorer on your computer.
  2. Navigate the following path to get to the etc folder:

C: > Windows > System32 > drivers > etc

Tip: To get to the folder quickly, copy the path and paste it into the bar at the top of the File Explorer window. Then hit Enter.

  1. Now, once you are in the etc folder, click on a blank area and press Ctrl + A to select all the items. Then press Delete on your keyboard or right-click on one of the highlighted items and select Delete from the context menu.
  2. When prompted, click the ‘Yes’ button to confirm the deletion.

Afterward, close File Explorer and launch Chrome. Try visiting a website and see if the error message has been resolved.

Fix 8: Restart the Internet Connection Sharing (ICS) Service

The internet connection sharing service is a Windows service responsible for name resolution, network address translation, and intrusion prevention, especially if you use an office or a home network.

The error may be showing up because this particular service is malfunctioning or not running. So, restarting the service should potentially resolve the problem.

Thus, follow these steps to restart the service on Windows 10 and Windows 11:

  1. Open the Start menu and search for “Services.”
  2. Click on the Services app in the search results.
  3. After the Services app shows up, scroll to the Internet Connection Sharing (ICS) service and click on it.
  4. Go to the upper-left corner of the Services window and click on the Stop button.
  5. After the service stops, click on Start.

Fix 9: Use a Virtual Private Network (VPN)

If you encounter the server DNS address issue when trying to visit a website, using a VPN could help resolve it. The Internet Service Provider (ISP) may have blocked the website’s DNS. You can get some reputable VPN software and bypass the restriction. Make sure to obtain it from a trusted source to avoid infecting your computer with viruses and other malware.

Fix 10: Disable Internet Protocol Version

IPv6 is the most recent version of the Internet protocol. However, IPv4 is still commonly used today.

As it turns out, some DNS servers and websites are not yet compatible with IPv6, which could be the cause of the DNS error you’re experiencing.

You can fix the problem by disabling IPv6 from your network adapter settings.

Follow these steps:

  1. Call up the Run command dialog box by using the Windows icon + R keyboard combination.
  2. Type ‘Control Panel’ into the search field of the dialog box and then click the OK button or press Enter on your keyboard.
  3. Expand the ‘View by:’ drop-down menu that is displayed in the top-right corner of the Control Panel page. Select ‘Small icons’ on the menu.
  4. Scroll through items on the list. Locate and click on “Network and Sharing Center.”
  5. Click on “Change adapter settings.” It is displayed in the left pane.
  6. On the page that opens, right-click on your connection (whether Wireless Network Connection or Local Area Connection) and select Properties.
  7. Locate and untick the checkbox for “Internet Protocol Version 6 (TCP/IPv6)” under the “This connection uses the following items” category.
  8. Now, click on the OK button and check for the error.

Fix 11: Perform a DNS Client Service Reset

Windows services serve the purpose of managing your system resources and system settings. They also run the programs on your computer. You can modify these services through the “Services” accessory on your computer. This allows you to troubleshoot problems and also improve security and performance.

You may be able to resolve the issue you are facing with the server DNS address by restarting the DNS client service on your computer.

The DNS client service registers a name for your computer and caches Domain Name System identifiers. If the service is deactivated, your computer’s name will not be registered and the DNS name query results will not be cached, although DNS names will continue to be resolved.

Also, if the service is stopped, other services that are explicitly connected to it will not be able to start. Therefore, follow the steps below to restart the DNS client service:

  1. Invoke the Run dialog box. You can search for its name in the Start menu search box, or you can press the Windows icon + R keyboard combination to open it quickly.
  2. Once the Run dialog box comes up, type ‘Services.msc’ into the search field and click the OK button or press Enter on your keyboard.
  3. Locate ‘DNS client’ in the Services list and right-click on it. Then click Restart in the context menu that opens.
  4. Close the Services window and check whether the server DNS address issue has been resolved.

Fix 12: Look Up the IP and Add It to the Hosts File

Some users reported that this solution had worked for them. However, it may not be effective since it still requires using DNS servers to query the IP. Nevertheless, it can give you more insight into the Chrome error. If you are still able to visit some websites, then follow the steps below; otherwise, move on to the next fix:

  1. Visit https://www.whatsmydns.net/#A/com.

Note: Type the domain you cannot visit in place of ‘domain.com’ in the above link.

  1. Copy the IP address as listed on the resulting page. Note that the IPs listed will generally be the same. Otherwise, copy the one that is mostly used.
  2. Go to the Start menu by pressing the Windows button on your keyboard or clicking the icon on your screen.
  3. Type ‘Notepad’ into the search bar. Right-click on it and select ‘Run as administrator.’
  4. Click ‘Yes’ when the UAC prompt is displayed.
  5. Once Notepad opens, click the File tab and click on Open in the menu.
  6. Navigate the following path: C:\Windows\System32\drivers\etc.
  7. Select All Files > Hosts and open it.
  8. Go to the bottom of the file and use the format 0.0.1 domain.com to enter the IP address you copied earlier, i.e. replace ‘127.0.0.1’ with the IP address you copied and replace ‘domain.com’ with the domain you queried in Step 1.
  • Press Ctrl + S to save the file.

Afterward, try visiting the problematic website again. The procedure we applied above will help look up the route locally before your DNS is queried. The domain to the IP address has already been pointed.

However, if the website still doesn’t open, then the fault is not from your computer. You can try opening the site on your mobile device just to confirm.
