I migrated from exchange 2003 to 2010 and successfuly removed the 2003 server, however i may have forgotten to assign a new routing master and i believe the information is in the Active Directory.
How do i cange the first administrative group from the old server (which is still the Primary domain controller) to the new server which is exchange 2010.
Tha managment console best practices has two errors showing it cannot connect to port 691 and port 25 on the routing group master. Now this server no longer has exchange on it as it was removed and deleted.(error'd when uninstalling so forcefully deleted).
