Have your problem been solved? Digging deeper I noticed that several key services related to RDP functionality were not running on the broker machine. Remote desktop app, Can one user simultaneously connect from 2 devices, RDS member not able to connect when creating custom RDP connection, Dell ThinOS 9.3 Server denying connection to RDS server, 2016 Server RDS Install - There are no available computers in the pool. Step 17. Desktop Management service, but it wont start. Cannot connect to any of the specified RD connection Broker servers. Date:
