I can't establish an RDC connection into certain PC's on my physical local network. I checked all the typical issues present in about 40-50 Super User, Stack Overflow, Server fault and Microsoft forums posts: the PC is up and running, the firewall is open [TCP 3389], I can ping the PC, I can even RDC out of the PC. Some forums suggest some exotic solutions based on the theory that there's a corruption in the OS, etc. but the comparisons below are on 2 identical PC's running Win 8 that I do not believe are corrupted. I also have this on a newly configured VM which I sincerely doubt has an OS corruption.
So I finally noticed that on a PC I can't RDC into, the System Properties > Remote tab is different (Control Panel > System > Remote Settings). I believe this to be my problem and I haven't found a post that satisfactorily explains it.
This is the System Properties > Remote tab on PC's that I can RDC into:

The difference between the two dialogues is easy to see when comparing; the Remote Desktop dialogue is not present in the second case. As easy as this is to see here, for me it wasn't so clear until I was comparing PC screens side by side. Sometimes you don't know what is missing when it's not there.
The only difference I immediately see between the two PC's is the PC with the Remote Desktop dialogue is registered in ADDS. Before I add the other PC to ADDS I thought it would be useful to find out if that's the real issue the dialogue is not present. Or, is there some other setting that turns on that Remote Desktop dialogue?
This suggests that I am missing a key concept with RDC. Based on the number of posts I see on RDC, this may also be many other people's issue.
