I'm facing a rather strange, and infuriating, issue with a recent Windows 2008R2 configured as a Remote Desktop server.
One one server, I can see that 2 RDP connection types are installed:
On the other, I can't add a new connection type for RDP6.1.
I need a connection type compatible with 6.1 for the simple reason that we have older thinclients that fail to connect to the new server (but have no problem connecting to our older Windows 2003 server).
All User licenses CALs are installed properly, all servers are up-to-date.
