Finding DNS servers

OK, this is another windows question, but you folks seem to know a lot
about the subject. Im trying to discover an easy way of finding out the
IP addresses of the DNS servers that are being sent to a machine
configured to get them from DHCP. If they were running any kind of *nix
I'd just visit some site and then do:
cat /etc/resolv.conf

Is there some file in Windows similar to resolv.conf? It's Windows XP
home edition if that makes a difference.
