When trying to RDC (i.e. terminal services connection) to a server I started getting the error:
The remote computer disconnected the session because of an error in licensing protocol
Spent a while figuring out exactly what I had to turn ON to get it working when in fact it was something I had to turn OFF.
The problem was I had installed the “Remote Desktop Services” role thinking it would enable RDC connections, when in fact this is a much more complicated beast that I think wants to enable the server to serve up tons of desktop sessions to many users vs. the single connection administration activity I needed. This new functionality comes with yet another licensing scheme from Microsoft and googling for a solution sent me down this path many times.
The solution: Remove the “Remote Desktop Services” role, and go to Start ->Control Panel->System and Security->Allow remote access . Doing this you find the familiar Remote Desktop settings and things work like I expected.
