Cannot view Ubuntu machine on network

Hello all!

I am pulling my hair out trying to figure out this problem I'm having.

I have 3 machines.

1: Win 7, 32bit
2. Win 7, 64bit
3. Ubuntu 11.04

My Ubuntu machine is visible and accessible on the network via computer #1 just fine, but I cannot view the Ubuntu machine on computer #2.

I can see my other Win7 32bit machine on the network.

All workgroups are the same and network discovery and filing sharing are all on.

Any suggestions?

I've had problems getting linux seen, but you should be good if it's seen on one 7 box. I would start by opening a Start/Run/cmd window in each 7 box and inputting ipconfig /all >%userprofile%\desktop\ip.txt, then comparing the two sets of settings.
