Sorry... let me post my script. I am using loadkey, but saved the keys by exporting them from regedit. This was working for me the first few time I tested the script but for some reason has stopped. I need to save the keys using savekey instead of regedit? Thanks, I'll give that a try and update in a bit.
code:
 ;This Script 
;determains CCD (Call Center Desktop) and lock if user is not 
;A domain Admin. If the PC is CDE it maps wkgroup and user drive
;and sets-up email profile if not present
