We are running NT 4.0 with the Novell IntranetWare Client V4.10 (970214) and Novell Application Launcher 1.10.
We have a large lab of PCs and an even larger collection of students who use the labs, thus roaming profiles are enabled and made full use of. Students share a common no-privileges STUDENT account to login to the local NT workstations and use their own unique Novell account for the server.
Every now and then a student will click on an icon on the NAL and will get the error: "Could not get needed resources for application [application name] to be launched [id=8].
Problem: Script execution failed ." And the application will not run.
This might happen to 4 people a day. It is seemingly random. Everyone else is unaffected and fine.
Once error this happens, the student is "cursed" and can no longer run most icons off the NAL. Even if they logout and shift to another machine, the curse will follow them.
If a "non-cursed" student logs into the very same machine after the cursed student logged off, they will invariably be fine. This proves that the curse is not machine dependent.
From my investigations, it appears the student's NTUSER.DAT file stored in their roaming profile directory (Windows NT 4.0 Workstation Profile) some how gets corrupted.
We do have a solution for the bug but it is not very good. We copy a virgin copy of the NTUSER.DAT file over the top of the cursed one.
This allows the student to do things again, but of course they lose any information formerly stored in the NTUSER.DAT file (registry information?). It also means they cannot fix the problem themselves and are thus doomed if they get the bug after-hours.
Question: Why is this happening? How do we stop it? Can it be fixed more easily?
