How to Flush DNS on a Windows PC

Performing a flush of the DNS allows you to flush and reset the contents of the DNS client resolver cache. During DNS troubleshooting, you can use this procedure to discard negative cache entries from the cache, as well as any other entries that have been added dynamically.

Below you will find the steps needed to flush your DNS on a Windows based PC using the Command Prompt:

Step 1 – Close all open web browsers and applications on your computer

Step 2 – Open the Windows command prompt by selecting the Start menu and entering “cmd” in the search text field box followed by clicking the “enter” key.

Step 3 – At the command prompt, enter “ipconfig /flushdns” followed by pressing the “enter” key. After a moment, Windows will display a message similar to: “Successfully flushed the DNS Resolver Cache” Once the message is displayed, the DNS will be flushed removing all incorrect entries.
