Win98 users on different Win98 machines sporadically (but not simultaneously) can’t access or logon Win2k without rebooting the Win98 client. User will be in and out of applications that require access the Win2k Server. Suddenly they can’t access the server at all. If you try to log the user off and back on again you get an error and can’t logon until rebooting the Win98 machine. This does not seem to happen if the user stays in the application that requires the server. The problem seems to occur more often when the server is working harder. Any ideas?
