I have a client that tries to maintain his own network. He has one domain controller and about 65 workstations. As users leave the company he changes the computer name to reflect the new employee. Over time the same physical computer shows up in twice in AD “users and computer” and under DNS. Example…old computer name may be “tjones” for an old user “Tom Jones”. As the user leave the company and the new user starts working at the company, he’ll change the name of the computer to the new users name…”jsmith” for an employee “Jane Smith” Is there a Microsoft tool or a way to remove the old computer names from “users and computer” and DNS?
