I am transitioning a single server network from old to new... New server is running on a new local domain with completely rebuilt AD structure but with same usernames etc.
Server 2003 Std SP1
Exchange 2003 Std
Server 2008 R2 Std
Exchange 2010 Std SP2
All is up and running on the new server but DHCP service is still being supplied by OLD server until email accounts have been transitioned. Have been trying to connect a client running Outlook 2003 but the connection insists on finding the old server on the OLD domain after removing the Exchange connection, restarting and attempting to join the NEW. Yes - entered the FQDN for the NEW server and the NEW server is reachable from the client. The connection seemed OK (underlined the server and user) when the new connection was made but upon restarting Outlook, the OLD Exch server was contacted and new OST was rebuilt.
Any suggestions or experience with this?
