When the state-capture phase runs while I'm deploying an OS image via the Microsoft Systems Management Server (SMS) OS Deployment Feature Pack, I get an error message and the process stops.

A. If you receive the following error during the state-capture phase

Program Error -
Scanstate.exe has generated errors and will be closed by Windows. You
will need to restart the program.
An error log is being created.

you probably omitted the /all switch from the parameters of the call to User State Migration Tool (USMT). Windows 2000 becomes confused if you don't specify an account, so always remember to do so.
