Ok guys, this one has me stumped. Our company has a few offices spread out over different cities. We have 4 different workgroups, 1 for each office. We'll call the workgroups "A", "B", "C", "D". My office is workgroup "A". File and printer shareing is turned on, on all computers on all workgroups and all firewalls are off. All machines are XP Pro SP2. The problem I am having is this. I can see all of the computers on my workgroup, but I can't see any of the other workgroups. I can ping those computers both by IP and computer name. I just can't see them through Windows Explorer, the workgroup or the computer names. Any ideas?
