I would like to know what the undocumented DNS cache cleaning does and how Windows Vista handles DNS cache?

It's saves the DNS and IP-address in a cache.

So it's not needed to be resolved again and will speed it up.

For example. Write "ipconfig /displaydns" in the command prompt in Windows XP.

I don't know if it's works in Vista.

If you're using a big HOSTS file like the one from MVPS.org you won't even need to flush the cache because the service responsible gets turned off during install.
