I had a 2003 domain with six server plus an exchange 2003 server. My company was purchased by a larger corporation and a trust was established between the corporate network and my domain. All email must go through the corporate 2007 exchange server. I have stopped my exchange services and disabled them after a sucessful migration to the corporate email server. The exchange 2003 has a/d and dns running on it. This server has many shared folders for the various users/groups. Shutting it down and rebuilding is not an option.
The problem exists where on occasions the workstations believe that the exchange 2003 server is where the email rresides. I had to uninstalled exchange and reinstalled and IIS a couple of times,
What is the quickest way to unstall exchange 2003 from the server and remove all it's references in the a/d, registry and etc?
