Got a fairly basic installation consisting of two servers: a DC (running 2012 R2) and a RDS (running 2012R2). The system is in production for about 2 months now. I recently noticed when trying to offer user support through session shadowing on the RDS server that the connection collection has disappeared.
I used to go to Server Manager > Remote Desktop Services and there I had a connection collection from which I was able to pickup a user and shadowing the session.
This collection has disappeared. When I go to Server Manager > Remote Desktop Services > Overview I do get the following message "A Remote Desktop Services deployment does not exist in the server pool. To create a deployment, run the Add Roles and Features Wizard and select the Remote Desktop Services installation option".
Strange, since it has been done ? Anyway, trying to run the wizard: on the top of the "Deployment Type" window, I read "A Remote Desktop Services Deployment already exist in the server pool"! Whatever option I chose, when clicking on next the following message appears: "Could not retrieve the deployment information from the RD connection Broker server <local servername>.
The connection broker service is running. Restarting it does not solve the issue. Nothing relevant shows up in the event viewer.
I can't tell for sure when the issue appeared. The last maintenance actions that took place recently were the installation of Windows updates and the removal of an older, disconnected DC (NTDSUtil - Metadata cleanup).
Any help would be appreciated.
