We do a lot of imaging and my techs many times do not name the computers the exact same name. So I have about 3300 computers listed in Active Directory but I know I only have about 1600. AD has been active for about 2.5 years so I have alot of excess baggage. I can see the active computers in Hyena and could delete from there but I take a chance that I will delete legitimate ones adn then we would have to go out and join the domain again. I know that I could go to DHCP and see who the active leases are but that would entail doing a ton by hand and I would think there has to an easier way. thanks
BTW they should give points for really good questions and I feel this is a great one.
