80071390 is ERROR_SHUTDOWN_CLUSTER. ExchangeGetComputerNameExW will return that when running on a cluster node and the cluster service isn't running. If this happened immediately after rebooting, maybe clussvc is still trying to join the cluster. Sometimes it takes a couple of minutes tojoin properly. If it's been a long time: Is the other node up and healthy? Do you have the File Share Witness quorum configured? Is that third machine up and running? (From a command prompt, run `cluster node`. If it prints out the nodes of the cluster, things are fine. If it prints out something like 'RPC service not available', then clussvc isn't running.) Look at the event log for event from Windows Failover Clustering, and if you're feeling particularly brave, look at %windir%\cluster\cluster.log (cluster.log has a lot of information, and it's easy to get overwhelmed -martin

Thank you Martin~ The ERROR almost happens immediatelywhen rebooting the master node , sometimes may happens immediately when rebooting the slave node, the system works healthy except the 2 Error . Refer to the Release Note another Error " MSExchangeTransportLogSearch 7005 " can be igored . Can Iignore the two ERROR ?

I've seen this exact set of errors on CCR whereas only the passive node reports them; meanwhile everything appears to work fine. Incidentally, the application of SP1 has caused them to cease
