I read this a while back and it is quite helpful to know beforehand. We had an instance of this at work a while ago where an OU of computers was accidentally deleted. You can recover the computer accounts easily enough but when they don’t recover with their machine password it still doesn’t help. This walk-through shows you how to set it up so the machine password is saved when the account is tomb-stoned and then restoring is a breeze. If there is a next time, we’ll be ready!
