I have a server running Windows Server 2012 and it only has the Hyper-V role. I have a VM also running Windows Server 2012 and it has the Active Directory: Directory Services and DNS ([example.com]) roles. It has been promoted to a domain controller for [example.com].

In the virtualization host I have joined the domain successfully. On a laptop on the network, it can ping my DNS that is inside the VM on the virtualization host. However, it can't resolve anything through the DNS.

I figured it was a firewall issue where the DNS had the firewall allow rule, but the virtualization host did not. I added that, but it didn't fix the issue.

On my laptop, I get "UnKnown can't find [example.com]: No response from server" immediately. There's no time out, it just comes back right away.

What have I overlooked?
