Maybe is better if you can give us some other details. Fslogix or something else... Seems an error on the profile... Try anyway to connect with mstsc and see if you have the same error
I have one user that experiences this symptom about once a month. While I haven't isolated the cause, the fix is to reboot the host to unlock files in use for his profile in windows, then I rename the profile from UserProfile to XXUserProfile. That gets a quick resolution, but not helpful if it's a reoccurring problem.
