I added the NETBEUI protocol, but my wife's win2k rig still can not see any others except for my other win2k rig and my win98 rig. The other 2 xp rigs are not shown, and I can't browse any of the files manually through explorer.
What is intresting is this pic:

All my other pc's have an IP address and a MAC address (what is a MAC address)?
Look at the pc that says LOUISE (my wife's name). It does not have an IP address and it says it's a printer server? WTF?
The other win2k rig in the garage can see all the pc's including the xp rigs. I'm scratching my head on this one. They all plug into the same router that is located in the garage. The pc's in on the second floor, we had to install a switch because of the way the phone company dassy chained the lines to the second floor. All the pc's have internet access no problem.
Any ideas?
