Here's an interesting scenario, anyone else come across this and have some pointers?

We have a nice healthy AD 2000 Install at present (yes, yes, ancient I know) with an Exchange 2003 Organisation. Its in Windows 2000 AD Native Mode, and in the near future were looking at a AD 2008/Exchange 2010 upgrade to get us closer to something a little more modern.

However, one of our Office Sub-Domains has been lost recently, due to liquidation and then IT not being given the time to decommission the servers properly.

So not only are in a position of manually cleaning up the old domain via NTDS Util, we've got to clean up the old Exchange Server entry as well.

User data/email on the old domain/exchange server is irrelevant at this point - this is just a clean up exercise as the lost Exchange server was a 2000.

Now, I'm thinking I need to simple 'Right Click-> Delete' the server in the Exchange System Manager, and clean up RGCs SMTP connectors and the Admin Group. then go ahead and clean up the Domain/Domain Controller meta data using NTDS Util.

However, a quick scan of the GC in the parent domain shows old sub-domain user accounts with mailboxes featured on the disconnected Exchange server.

Am I right in thinking that the GC will therefore stop the manual removal of this server?

Is there some experience out there with some pointers for this?
