I have 3 workstations on a peer to peer network. All are running win98 se. When a try to connect to any of the workstations, I get a mprexe fatal error. The machine then hangs and I have to reboot. This seemed to start after I changed a motherboard out on one of them, since then I put a new hard drive in and reinstalled the OS. Still get the same error. Sometimes I can connect with no errors, so the problem is intermitant. Could there be a problem with the hub?
