When publishing an App Layering image to PVS using Offload Composting, it may fail. 

When entering the user name on the PVS connector, user domain\user format.

Problem Cause

The connector was configured with a domain account but it was only configured as User instead of domain\user.  This will cause the Compositing Engine to authenticate to the file share as a local user computername\user even though the user was actually a domain user.
