Hi team
Now if we shutdown Exchange 1 all the users are automatically redirected to Exchange 2.
DNS round robin seems to be working fine.
But when all the users were redirected to Exchange 2 i see that users cannot receive emails internally and externally.
Then we checked on Exchange 2 server, Queue viewer and found that Exchange 2 is relaying on exchange 1 mailbox for SMTP but Exchange 1 is down and users cannot receive emails on their mailbox.
Can you say me what could be the issue is this related to DAG.
Also i think i should inform you that when DAG was created we have single nic, Later we created another nic and enabled replication on it.
Awaiting for your reply..
