Student folder mysteriously emptying.

OK folks how about some help please with this strange situation. My Win 2K server and it’s brood of XP workstations has recently started throwing up a real baffler to me. When successfully logged on as a specific student and attempting to run a software package I’m getting a message telling me the programme can’t run because it is not able to locate in this case a student folder tamsinb on our server. First it happened in the Blackcat Fresco programme but today it also happened on a couple of machines running MS Publisher – with the latter it wasn’t a fall over case and choosing the correct user folder located the students work. With the Blackcat software it just refuses to run.

This has been a progressively worsening problem over the past 6 weeks. Also about 2 weeks ago tamsinb went to open her work and the folder was empty. A restore from our Veritas backup resolved that but yet again today the folder had been emptied and needed a restore. I have since changed tamsinb’s profile and given her a new folder to which I copied her existing work.

I’m totally baffled, anyone encountered this sort of problem before and got any ideas please?
