Hyper-V Error – An Authentication error.

Hyper-V Error – An Authentication error has occurred. The Local Security Authority cannot be contacted.

Today I was trying to connect to a Hyper-V Virtual Machine when I started to get this error on all of the VM's on that particular host. I was connecting to the Hyper-V host via a Windows 8 Workstation via the Hyper-V Manager.

At first I thought it was an issue with my account, but it wasn't. After hunting around for ages and running out of ideas, I stumbled across the obvious. The Hyper-V host didn't have the correct DNS servers set.

So I changed the DNS Servers to the correct ones that were being used in my Domain and bob was my uncle!

 

Hope this helps!

    I’ve acquired a 2012 server that someone else set up, and I’ve been trying to resolve this error for weeks now. I’ve looked at the solution you’ve described, and I want to give it a shot. But the virtual switch on the server doesn’t have an IP address. No other services have been bound to it except “Hyper-V Extensible Virtual Switch”. Can you imagine a reason for this?
