I have Exchange 2000 on a Windows 2000 server. The 2k box is also a root forrest server and domain controller and yes I know that's bad. This Exchange box was the first one ever installed, upgraded from 5.5. It has no mailboxes, etc. All I know is that when I turn off the info store and associated services on that 2k box, the other Exchange servers fail (they start but mail stops delivering ).
How do I get rid of this first Exchange installation? I have another Exchange 2003 box that is not a domain controller that I want to be the "first" "main" or whatever it is called instead of the old one.
Thank you for any help. This is my first step in removing the existing domain controller, which is also the root server for our domain.
