Using Remote Desktop b/w two Win XP PCs

Hey everyone,
What would I need to do in order to use Remote Desktop between two Windows XP Professional computers running on a home network. I have Remote Desktop enabled on both comps, but when I run “Remote Desktop Connection”, I can’t find my computer in my network.

Do I need to setup a VPN between the computers prior to using it? If so, what IP address would I use? 192.168.1.x where x is the number my router provides for the other computer?

Thanks!
