Thanks for the reply.
The file will run post logon if I manually execute it and it performs like normal. During the clone process I am using quickprep. The only time I use Sysprep is for copying my default profile prior to cloning.
I've looked at the linked page, and I may consider going to something like that if I can't find a solution. I'm really hoping I can figure out why this has worked for two years and is not now.
