We currently have 2 Exchange 2010 servers with DAG setup at the main office location. We want to setup a 3rd DAG member across WAN. Does anyone have any ideas on how to setup a DAG member across the WAN.
Site 1: 2 Exchange 2010 Mailbox servers running in a DAG, 1 Hub/CAS Server
Site 2: 1 Exchange 2010 Mailbox server and 1 Hub/CAS server
