Here is the situation:
SmallCo bought a rather large facility from BigCO. As part of the purchase, BigCo left the infrastructure in place, and a few machines related to facilities maintenance. One of these machines runs a sugar silo, and runs software created in-house by BigCo. Unfortunately, BigCo abruptly shut down all their servers, packed them up, and shipped them off, orphaning the facilities related machines. To make it worse, BigCo was paranoid about user rights, and had lots of things locked down via GPO. Even local administrators can't bring up Taskmgr, for instance.
I was able to create a fake domain by the same name as the one BigCo had, and that finally let me remove the machines from the domain. Now I am stumped about what to do about all the restrictive GPO settings. Is there any way to remove the GPO's, or set everything back to a default state?
Thanks for any suggestions.
