No, I always say, DNS, DNS, DNS, lol. Yes, the preferred DNS server on the NIC settings should generally be the IP of the server. Like you said.
He has a workgroup, correct?
Here is an interesting copy from one of my posts:
When the main screen is open, there is an Advanced tab on the right. Then at the lower left, there will be Settings. 2011 should have an RD Gateway, which is why the router doesn't need port 3389 open, and you can get to any computer remotely without port forwarding.
You can try setting up the RD Gateway so it is set only for that -- mostly the middle boxes. Or skip RD Gateway so it remotes directly to the computer. You may have to use the FQDN on the computer in question so if it is "Computer" it would be Computer.domain_name.local. But, you don't have a domain but you do have the four letter one called Raish or something.
Sort of sums up a little bit. Question: Can you actually change the connection routes with RDC by changing the Option settings under Advanced?
And, no one needs luck when you're around. Nice work.
