Nino_BilicMy apologies for not providing more detail, I'm still trying to work through the problem. I've applied the update to 1 of 6 Exchange servers in our environment (across 3 domains, each domain has 2 servers in a DAG). I placed the 1 server I have applied the update to in maintenance mode, and part of the process for us runs Suspend-ClusterNode on that server. However, after applying the update and running the Extended Protection script it seems like the cluster service totally stopped, and I had trouble bringing it back up. Once it was running again, the Exchange cluster node was reporting that it was in a down state, and running start-clusternode on it froze up the Exchange management shell window.
I am relatively new to administrating exchange, so please let me know if there is any other information you need that I may have left out.
