Dear Experts,

I am currently having some serious problems with my exchange 2010 dag environment running on 5 exchange mailbox servers and 14 databases. 3 mailbox servers holding database copies and 2 mailbox server are being used for only heartbeat for now.
 

2 exchange mailbox server (ex01 and ex03) are on the 10.78.133.0 subnet.  (10.78.133.143, 10.78.133.150)
1 Exchange mailbox server (ex02) is on the 10.65.65.0 subnet    (10.65.65.100) (All 3 mailbox servers are on one site)
hw01 - mailbox server (seperate site)
nw01 - mailbox server (seperate site)

The cluster is on a node majority mode

dag ips 10.78.133.50
10.65.65.50

Earlier this morning, ex02 ip went offline with the following event log 1135 and 10.78.78.50 dag ip came online and 10.65.65.0 was offline. As a result all of the databases on 10.65.65.100 went in a failed state and 10.65.65.100 ip went unavailable  and was giving errors like the network manager could not be intialized.

after sometime and a reboot ex02 came back online, but ex03  10.78.78.150 ip became unavailable and its database went into failed state. I am not sure about ex03,  why did it go out and how can i bring the ip to an available state

Would need your help in the matter?

thank you
