We have an RDS Server Farm with three 2012 R1 Session Hosts, and a 2012 R1 RDS Licensing Host. One of the Session Hosts also has the Broker, Web Access and Gateway Roles.
Occasionally, when we go to Server Manager, Remote Desktop Services to check user connections, the Servers that were added are missing. In RDS Overview, we get the message: "There are no RD Connection Broker servers in the server pool." We cannot access any of the RDS settings or sessions.
In the past, we have added the Servers back and it seems to resolve the issue temporarily but it keeps happening.
Currently, the issue is happening to the RDS Licensing Server, and when we try adding the Servers back - nothing happens.
