I have a seen this problem with a large numbers of customers that are running Build and Capture with MDT on a Hyper-V Cluster I VMM.

The problem is that the virtual machine that runs the build and capture process is shutting down in WinPe while capturing the wim file.

The solution is to disable Heartbeat in the Hardware Configuration on the “build and CApture” virtual machine.

I have not seen this error on a standalone Hyper-V server.
