I was setting up a PoC with 2012R2 RDSH environment, adding the RDSH hosts to the connection broker. This went without errors, but when trying to add the servers to a collection I got this strange error:
- Require user authentication for remote connections by using Network Level Authentication
- Set client connection encryption level
- Use the specified Remote Desktop license servers
It appears that the issue remains in Server 2012R2, 😐
Unlinking the GPO’s which configured one or all of these settings and deleting all subkeys in: HKLM\software\policies
And rebooting the server fixed this problem for me.
