Short description

- I have two Exchange servers in DAG. Both servers are having Client Access role installed in it.

1) Exchange-1 (Mailbox and CAS)

2) Exchange-2 (Mailbox and CAS)

While monitoring the servers, I noticed that the RPC operations per second is normal in Exchange-1 and in Exchange-2 it is showing as zero.

However, at times say 3-5 times a day, I get RPC Requests Outstanding (=3). At the same time, rpc operations/sec is 0

Can anyone help me in identifying which will be the Client Access Server to which clients will be connecting (Exchange-1 or Exchange-2 or both)?

And the reason why rpc outstanding requests is greater than 0 when there is no rpc operation/sec.
