If you find after messing with the settings on 2012 R2 you find that your computer is being dropped right off the bat, you click connect, and its like nothing has happened, it may just be that the certificate you used initially is no longer valid. To kill off the old cert, open mmc, add certificates, go to remote desktop, right click on the terminal server cert, and delete it. Reboot. Once you are back up to the login screen, try RDP again. This time it should take.
