SBS2003 - cannot load local profile

I have one user who continually gets the above message when trying to log on.
If she shuts down, it works OK next time she logs in. Normally this PC is
left on as hse needs to be able to log in from home using RDC.

I have deleted her user name on the local PC and recreated it, but she still
gets this error.
Is it possible that her profile on SBS is the faulty one? If so, how do I
delete and recreate her roaming profile without losing her Exchange mbx?
