Windows Server 2008, “The requested operation requires elevation”

I'm trying to flush the DNS cache using ipconfig /flushdns at the command line but I get a message saying The requested operation requires elevation. Could someone help me in figuring out the reason behind this please?

Flushing the DNS cache requires UAC elevation, as do some of the other functions of ipconfig.

To run them, you'll need an elevated command prompt. Right-click cmd.exe and select "Run as Administrator".
