i would like to clear DNS and Route using command does anyone know how to do this?

Let's try a Google search for [search]DNS clearing[/search]

Found from the google search

The following command performed at the Windows command prompt (Start -> Programs -> Accessories -> Command Prompt), flushed the resolve cache and took care of matters.

ipconfig /flushdns

This flushes the DNS cache on modern Windows 2000 or XP boxes (maybe older). You can also use the nslookup command to see what the DNS resolver is actually seeing.
