Flash Windows Vista / XP DNS Cache With ipconfig Command

by admin on November 13, 2007 · 5 comments

in Windows Vista

ipconfig is a Windows XP / 2000 / 2003 / Vista command utility that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol DHCP and Domain Name System DNS settings. You can use the same tool to clear out Windows DNS cache. This command has /flushdns switch 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.

Command to Flush DNS Vista

Login as administrator

Just open command prompt ( Start > Run > and type cmd > Press [Enter] key)

Type the following command to flush the DNS resolver cache when troubleshooting DNS name resolution problems, type:

ipconfig /flushdns

As usual you read help by typing the following command:

ipconfig /?

Please see ipconfig command help page for more information.
