On exchange 2010 DAG with 2 nodes the cluster name &nbsp;is offline and cluster Ip address is in failed state.I tried to bring it online but it kept faling.Also file share witness is in failed state.Also in the EMC org-mailbox DAG I have 2 networks.One which has public networks(network1) which are in failed state and the replication is not enabled on it, and a another network in which has private network cards and replication is enabled and status if working.<br />
I haven't got much experience with DAG so let mw knoe if need any further information.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
