I need to to the real world steps (not the microsoft version) for removing an old Exchange 2003 server.
I have a 2003 AD domain that I have run the adprep for Server 2008. I have installed two server 2008 machines one running Exchange 2007 (hub or gateway) and one running Exchange 2007 (mailbox or backend). I have moved all the mailboxes using the Exchange 2007 tools and shut down mail services on the old 2003 exchange server. Everything seems to be working fine so I want to remove the old Exchange server and rebuild it for something else. Since it is integrated in the forest I was wondering what is the cleanest way to remove the server without leaving traces in AD.
