If only one of the computers running XP is connected to the NT server it works fine. The problem is when I try to connect both XP computers to the network then they both disconnect. They think they are being connected to a workstation instead of a dedicated server. I replaced two Windows 98 workstations with the XP workstations so it is not a problem with my network. The problem seems to be how the XP workstations view the network.
Thanks for the help.
