DNS Resolving on Client Computers but failing on DC

My Domain Controller is failing to resolve any DNS records:

However all the client Machines that are connected to the DC can resolve all the DNS records with no issues:

I am running a Virtual Switch, VPN and a few other things on the system if this may be any help to solving the issue.
This is really messing up a lot of things as I can't use any RPC features which prevents me from updating policies across the entire network.

My DNS setup doesn't seem to be incorrect.

Hopefully someone may have an answer to this issue, if I find a solution to the issue I will post it here.

    The simplest solution may be to remove the VPN and routing from the domain controller.

    Multi-homing a domain controller will always cause no end to grief for active directory DNS

    The RRAS role should never be installed on a domain controller. Simply move it to another instance of windows.

    The hypervisor should only have the hyper-v role installed. Stand up virtual machines for the various roles, etc.
