I was configuring a Lab Management setup today and after a reboot of the Hyper-V host, I found I could no longer RDP to the host machine. The error message was a rather cryptic “An authentication error has occurred. The Local Security Authority cannot be contacted. Remote computer: hvlabhost”

After digging around checking the appropriate domain controller, manually configuring the time service and a variety of other potentially useful but largely irrelevant settings, I found the following helpful blog entry.

“Hyper-V Error: An authentication error has occurred. The Local Security Authority cannot be contacted.”

I had a bit more of a look through the rest of the blog and likely what I found.
