Exchange 2010 SP3 x2 on Server 2012.
Set up new DAG - when adding first database copy i get the error:
A source-side operation failed. Error An error occurred while performing the seed operation. Error: A timeout occurred while communicating with server 'BERLIN'. Error: "A connection could not be completed within 15 seconds.".
The database shows up after a refresh anyway as Suspended, and doesnt seem to be doing anything. Copy Queue Length is sitting at 27k.
Google suggests this is a networking issue however there ping times are nice and low between all IP's.
Exchange Replication is enabled on all networks at the moment.
What should I do??
