I've encountered that symptom twice; once back in the Windows 3.1 era, and then again more recently. The answer in the old days was to eliminate all protocols other than TCP/IP -- it turns out that Windows networking will work just fine (better, even!) if you do not have NetBEUI installed as a protocol. Years went by. We recently had a power outage and shut everything down, and when we turned things back on, the network (seven PC's and one token iMac) fragmented into pairs or triplets. None of the boxes could see the entire workgroup. I discovered that if I made one Linux box the master browser for the entire workgroup (using samba), everything stabilized and everyone started working together again. Takes a few minutes for the broadcast messages to make the rounds and for everyone to find each other, by the way. Who knows, it might simply be a matter of turning on the machines in the right order!
