I have a 6 peer to peer network with 4 Compaq PC's running win98, 1 HP running winme and a Toshiba laptop with xp home. One of the compaqs has a HP1100 printer attached to it which is the one that disappears from the lan which is a 100Mbps lan from the hub to the nics I also changed the hub but still no luck the thing is when it had netbeui and ipx/spx on all the pcs it used to work fine. What I did was clean it up and only have tcp/ip using the 192.168.1.X addresses which also was there when it had the netbeui and ipx, but upon removing these other protocols the pc with the printer in a maximum of once or twice in a week will dissapear from the lan until the user restarts her pc.....I am going nuts about this all the cables and wiring have been rechecked and are to the 568B Catagory. Also the PC's doesn't have any viruses as I have scanned them already. Please help with suggestions on what else I should try?
