We have a peer to peer network that includes nodes with the XP, Me, 2000 and 98 OS. Last week the 98 PC's dropped of the work group and then one by one all the computers dropped off. When I looked in Mu Network Places to see if I could find any of the computers they were not in the workgroup. I checked the name of the workgroup on the XP PC's and they all belonged to the same workgroup. I changed all the computers to a new workgroup and they could all talk to eachother again. Anyone know why this happened and what I can do to fix it?
