I added 2 2008 R2 servers and configured and migrated ADS. transferred 4 FSMO roles and DNS server. Everything seems working except Exchange.
when i switched of old 2003 primary server, incoming and outgoing mails stops, how ever i can see it in queues.When i restart Dc, mail start flows and i am not losing any mails.
Directory access can see new servers and auto discovery is enabled.
