I am setting up a small office network. There are 2 XP machines. There are 2 folders on one of the XP machines that need to be shared. There is no server, it is a peer to peer network. The 2 XP machines have static IP’s. The second XP machine will connect to the network and access the host XP folders but after 15 to 30 minutes it no longer sees the other machine. I am able to ping the host XP machine while the problem is occuring. I expect that it is a DNS problem but I don’t know what to do with it. The XP desktop that loses connection is SP 3 and has Norton antivirus installed. I have tried shutting down the firewall and disabling Norton but the problem continues. I am thinking of deinstalling Norton but hate to do so because I’m not sure that is causing the problem. I am going back to the customer location tomorrow. I would appreciate any ideas to help get this resolved.
