We are having an ongoing problem at one of our high schools where the connections are not always clearing on logout. All of the students at the site have unique logins, and all are configured with Max Simultaneous Connections = 1. Sometimes when a student logs out on one computer and tries to login on another computer later they are denied, and when we check it still shows the student logged into the first computer. This has even occurred when another student has logged into the first computer.

We are running NetWare 6.5 SP4 on all the servers at that site, and the workstations are running Win9x/2000/XP. There doesn't seem to be any pattern to this behavior, and we've tried updating the NWClient and ZfD agent to no avail. The student accounts even have time restrictions that expire at 9:00pm, but these connections have even held overnight.

Does anyone have any ideas? Please? We're totally stumped >:-(
