Is the IP address correctly configured on these network resources in the cluster ?

Yes, the only thing different is that the Cluster is on a different network than the Dag Nics. &nbsp;Example;<br />
The DAG Nic1 are 10.10.10.1 with 255.255.255.0 and DAG Nic2 is 10.10.10.2 with 255.255.255.0 and the DAG Name (DAG1.domain.com) is 10.1.1.132 with 255.255.0.0. &nbsp;

My problem was slightly different. I ran test-replicationhealth command from Exchange PS and noticed that problem is pointed to one of my DAG members. Simple reboot fix the problem.<br />

Thanks for getting back to me!

I currently have a DAG setup between two mailbox servers.  When I expand windows load balancer and go to the Network the DAG cluster shows Unreachable.  The status is Partitioned and the status on each server  is Unreachable.  I can ping the interface from both servers without any issues.  Can anyone suggest why ny DAG network is showing down.
