I have been using Hyper-V to test parts of my deployments in sccm 2012 r2 for some time now, and yesterday, they would not complete. Turns out the error in the topic is what is causing it. See below for a screenshot in devmgmt of the error causing the machine to be unable to access network resources.
of the solutions tried so far, I have rebooted, and uninstalled/reinstalled the Hyper-V role.
