How To Fix ERR_NAME_NOT_RESOLVED Errors in Windows

There are few things more frustrating than wanting to check on the football scores or the latest movie review and seeing ERR_NAME_NOT_RESOLVED in your browser. The chances are that you’re using Chrome if you see those words. Edge and Firefox say different things. Regardless of the syntax, the frustration is just the same.

The ERR_NAME_NOT_RESOLVED error refers to a fault in your computer’s DNS setup or a typo in how you spelled the URL. The latter is simple to remedy, but the former takes a little more work. Not a lot more, though, you will be pleased to know.

As with any network error, the first steps are straightforward. Check your internet connection, check a different website, use a different browser, reboot your computer and router, and retest. If that doesn’t fix the error, then one of these steps will.

Flush the DNS Settings on Your Computer

1. Open a Command Prompt as an administrator.
   
2. Type ipconfig /flushdns and hit Enter.
   
3. Type ipconfig /renew and hit Enter.
   
4. Type ipconfig /registerdns and hit Enter.
   
5. Retest using the same browser and URL.
   

This process will flush the DNS cache, forcing Windows and your browser to reload DNS afresh. The method addresses most ERR_NAME_NOT_RESOLVED errors, but if you still see it, try the following process.

Manually Configure your DNS Servers

1. Open Control Panel and navigate to Network and Internet.
   
2. Navigate to Network and Sharing Center and select Change adapter settings in the left pane.
   
3. Right-click your network adapter and select Properties.
   
4. Highlight Internet Protocol Version 4 and click the Properties button in the window.
   
5. Select ‘Use the following DNS…’ and add 8.8.8.8 and 8.8.4.4 in the spaces. Click OK. These two servers are Google’s DNS servers and are very, very fast and accurate.
   
6. Retest using the same browser and URL.
   

Change Router’s DNS Settings

If you use a router, you may also need to change the DNS server settings there. Some cable companies specify the DNS server used within the router config, which can override your Windows settings. If nothing changes after making these modifications, it might be worth checking your router.

In the end, one of these steps is sure to fix ERR_NAME_NOT_RESOLVED errors. For most cases, flushing DNS through the command prompt and forcing a reload of the config is enough to fix the DNS error. If not, the other two processes definitely will.
