Exchange Server 2016 CU7
Windows Server 2012 R2
All Exchange services suddenly stopped working except "Search host controller" and "Server Extension for Windows Server backup"
Topology gets error 1053 if I try starting it. Most other servicess get 1068 due to dependencies.
Interestingly some non-exchange services were disabled. "WWW Publishing Service" and "WMI" I was able to enable and start these and they remain enabled after a reboot.
Not sure what caused this.
Tried running updates but it fails to do a security update for CU7 (KB4045655).
I am in the process of downloading the Exchange ISO to see If I can do an installation repair.
If I restore whole VM from backup would there be any AD complications as there is separate Domain Controller?
Any suggestions would be appreciated.
