We have the following servers all Windows Server 2016 with all patches installed as of this posting:
1. Gateway: RDP Gateway, RDS Broker, RDWEB
2. RDS01: Remote Desktop Session Host.
3. RDS02: Remote Desktop Session Host.
4. PDC: Domain Controller and Licensing server.
When I attempt to create a collection, I get the following error: The program cannot open the required dialog box because no locations can be found. Close this message, and try again.
Note that the default group is not there. I have never seen this error before and I've been using Windows since the NT4 days. Any clues?
