How to Clear and Reset DNS on Windows 10


When browsing the internet you encounter a large number of 404 errors, or web pages fail to load.


This issue maybe related to a problem with your DNS (Domain Name System) and maybe fixed by forcing the computer to clear/reset DNS.  

DNS is like a digital Yellow Pages, but rather than matching peoples names, addresses and telephone numbers. DNS is used to convert IP addresses to domain names. These addresses are stored locally on your computer in something called a “Cache“. Clearing DNS will  force your computer to re-download the IP addresses and domain names, thus updating the Cache.

  • Select the Windows Start Menu
  • Locate and right click on the “Run” command
  • From the Quick Menu select “Run As Administrator
  • When prompted enter the administrator username and password
  • Enter the following command syntax exactly (use copy and paste if in doubt about syntax accuracy):
ipconfig /flushdns
  • Hit the Enter key
  • Windows 7 and 8 will notify you that you have successfully flushed the DNS cache. However Windows 10 will not.
