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:

20160610_Error_adding2Collectionwith an eventid 24584:

As it turns out, this is a cryptic error which only appears if you have an active GPO on the RDSH server which sets one of the following:

  • 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.
