We have a new Windosw 2016 server with Exchange 2016.
This was working fine until we installed the latest updates.

Specifically "Security Update For Exchange Server 2016 CU6 (KB4045655)".
This tried to run but then displays "Failed to install 29/12/2017"

The problem is that all the Exchange services are disabled and isn't working
