Account change fails-winxp

[europanorama]

when a task is running in account 1 and i want to switch to acount 2(e.g. administrators) in winxp this error is showing:
csrss.exe-couldnt start-basesrv not found- new installation could solve the problem.
my problem: it was ok one time on both drives, one is a copy of the other. both have the same issue. thanks a lot

What kind of task?
If you let the task finish does switching user work?

found out that open window/directory is a task. switching is now running.
log-out:
what i do not understand is: is it for security reasons logging out from the accounts when shutting down, not switching? thanks
