After the Windows 10 version 1803 upgrade on April 30, 2018, my System Image Backup keeps failing withe two messages. "The backup failed" "The RPC server is unavailable (0x800706BA)".
Note that the System Image Backup worked before the upgrade. The upgrade completed OK and I have not found any other issues.
I checked that =1= The RPC (Remote Procedure Call) service in Services is active and running and =2= the DCOM (Distributed COM) is enabled. There used to be a SYSTEM disk when I did the defrag, the defrag does not show the SYSTEM disk in version 1803.
Is it a bug, or is there a fix or should I try the Image Recovery (that might fail as well).
