XP won't show up in the Workgroup

[SagaLore]

I have three machines - my XP tower, a spare XP laptop, and my wife's macmini. My tower won't show up in the workgroup. XP Firewall is disabled, file and print sharing is enabled. NETBIOS over TCP/IP is enabled. They all connect to my linksys router.

For some reason I can't get the Tower to show up in the workgroup, even at the Tower.

Nevermind, I figured it out. Under Local Area Connection, the file and print sharing was not checked.
