Beginning with Win2K TCP/IP and DNS became the favored protocol and name resolution scheme as opposed to netbeui, netbeui over TCP/IP, and WINS. Netbeui needs to run OVER TCP/IP to be routable. Anyhoo, make sure netb is installed on both. Make sure Client for Microsoft Networks is installed all around, as well as File and Printer Sharing. If they can ping you are just about there. Also, to make things easy, create the same logins on both computers to get around the password prompt. And make sure you have good anti-spyware and virus protection. Installing MS networking is analogous to putting up a neon sign saying "Hack Me and Infest Me."
