We have 2 Exchange 2013 servers on Windows 2012 R2. One in our corporate office and one in another city. The witness server is in our corporate office (Consulting group put it here and never told us about it until we lost both servers, I am trying to get it moved). However, I continue to get warning messages Event ID 4123 "Failed to get the boot time of witness server 'witness.domain.com'. Error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) These show up a few times a day.
I ran Test-replicationhealth, everything passed except QuorumGroup. this failed with "Quorum resource 'Cluster Group' is not online on server 'exchangedr'. Database availability group 'DAG' might not be reachable or may have lost redundancy. Error: ..."
Any ideas what could be causing this? We also cannot reboot either server without having failed contentindexstate after the reboot. We were told this is normal and it will go away, and it will after about 4 days. Makes doing maintenance a real pain. Let me know if you need more information.
