Re: Question on Domain
I will answer you but first I want to say that this is a moral grey area. If you do something that damages their property you could be liable. This may or may not include you paying for the time that others will spend repairing the damage you've done, the equipment itself, and not to mention potential criminal charges. Now that I've addressed the disclaimer I will also mention that this forum doesn't allow discussion of any malicious activity (such as cyber breaking and entering). Bypassing your Board of Educations information security policies may fall under that rule but for the sake of discussion, and because you have administrator rights, I will answer under the assumption that you're doing this in a "white-hat" environment.
How fast they may notice that you have removed a computer from their domain depends entirely on what AD auditing/monitoring they use and how much of a priority they put towards securing their endpoints.
What exactly are you trying to do that they've locked you out of doing?
