The file that is causing the problem, UsrClass.dat, and its found it residing inĀ 
C:\Documents and Settings\Current User\Local Settings\ApplicationData\Microsoft\Windows\UsrClass.dat
Rename the file. The file is going to be recreated and this will eliminate the login error the user was getting. When everything is working fine, just delete the old UsrClass.dat file.
