I am suffering a similiar issue. I am tryign to prep some windows 7 machines for deployment in a lab. In that lab students will log in using their AD (active Directory) accounts. I would like, when a student to log in, for the computer to create an accoutn that mimics the default (administrator) in format and setup. I was told that sysprep will do this, however I am receiving the same errors that Crowe was, and changing my syntax did not fit it. I have stored my unattended.xml in the sysprep folder and I am making no progress whatsoever. Any thoughts or ideas? if I can offer any more information i will be glad too.
