I have done everything I can find to do - I have installed RDS services, I have purchased licenses, I have defined my server to be the RD Session Host server, the RD Licensing Server, and I have installed the licenses. I had the licenses defined as per user and installed the purchased licenses as per user, but it didn't work (licensing error below). I have rebooted. I then changed the licensing mode from 'per user' to 'per device' as there is an unlimited license for that in RD licensing. This doesn't work either - same error. So I took things a step further as per some online advice - I also set up my server as the RD Connection broker server and the RD Gateway server. Still get the error...also I can't find a way to directly access 'RD Session Host' utility...that seems to be an issue for lots of people though it is an aside.
The licensing error says 'The licensing mode for the Remote Desktop Session host server is not configured' and the grace period is expired. I cannot connect to this server via Remote Desktop Connection.
I have attached a screenshot of the RD licensing diagnoser. Thanks, Dawn
