We had an exchange 2010 server called E5, it was doing HT & Mailbox from a VM. The hardware was pretty bad and couldn't support multiple exchange servers so I moved it off to a physical box and powered off the VM.
So here's the question. When the other VM on that platform didn't power back on after a power outage (it was corrupt) I powered up the old EX5 VM, renamed the server to EX3 (to replace the one that died), deleted the AD account, joined it new to the domain, and re-added all the mailbox databases one at a time. Things seemed to be working fine.
However, when I launch the EMC it tries to connect to EX5 and fails! It should connect to it's self, as it is now EX3. Is there a step I missed? Do I need to tell the exchange services on that VM that it is now EX3? Or is there a way to just point the EMC on the server at its self once again?
