If you think you can just delete the extra local profile stuff from domain accounts before imaging, think again.

Here is the skinny:
Regedit HKLM->Software->Microsoft->Windows NT->CurrentVersion->ProfileList-> Look for 2 sid's that are the same except 1 has .bak. Rename the one without .bak, .ba Remove the .bak from the one with .bak Change the refcount and state to 0 on the one you just removed the .bak from save and happy, happy, joy, joy....
