VSS mapping failed with Windows Server 2012 / 2016

"Client has Windows Server 2012 R2 running P5.4.2
Client is a virtual machine on Hyper Visor. Client is Windows Server 2016.
Attempting to use the MS Windows VSS Setup on this client but the job reports
"Failed to create a mapping from /E /Y""
I was able to get VSS backup working on windows server 2016. Delegation needs to be enabled on both servers, and the user account running archiware on both servers must be in the backup users group in AD.
It is now working but there are periodic failures to map drive letters in the VSS section of the client. If I reboot the client process on the target server it resolves it for about 5 days
