Recentemente ho visto questo warning su un server windows 2012 R2 RDS (remote desktop services) with the license service "on board":
“Remote Desktop Session Host server is within its grace period, but the RD Session Host server has not been configured with any license server”
To activate the licenses or better to hook the RDS service to the already inserted licenses you must launch GPEDIT.MSC and go to:
Computer Configuration > Administrative Template > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing
Here you will find two policies to configure:
In the first one “Use the specified Remote Desktop license servers” you need to specify the license server (it can also be localhost if the service is on the same server).
In the second one “Set the Remote Desktop licensing mode” It should be specified the license type per device or per user.
