Compare AD Computers to CM Computers
It comes up all the time when I want to know if anything in AD is not listed in CM and has a client, etc. If you work for an organization that is blessed with having excellent asset management, you could compare CM directly against your CMDB. But, everyone is not this blessed as it turns out. And reality being, you really should compare everything in AD to everything in CM. If its a domain joined computer, you'll probably want to know if it is or is not being managed by CM.
