On an existing Netware network with a Netware 6.5 server and 15 Win XP workstations running Netware client 4.91, every other day, while all workstations are logged in, one of the workstations has the Netware client pops up and request the user to log in again asif they right clicked the Netware icon on the task bar and selected login.

This happens to just about every user atleast once a month (all using their own workstations).

What makes this really strange, is the User Name is always filled in with the name SYSTEM in upper case. There is no login on the server for a user named SYSTEM. They have to re-enter their correct username and login to continue.

Does anyone have a fix for this?
