Configure License Settings for an RD Session Host Server
Applies To: Windows Server 2008 R2
Each user or computing device that connects to a Remote Desktop Session Host (RD Session Host) server must have a valid Remote Desktop Services client access license (RDS CAL) issued by a Remote Desktop license server.
To ensure that an RD Session Host server can contact a Remote Desktop license server to request RDS CALs for clients, you need to do the following on the RD Session Host server:
Specify the Remote Desktop Licensing Mode
Specify a License Server for the RD Session Host Server to Use
To be alerted to possible licensing configuration issues, use Licensing Diagnosis in Remote Desktop Session Host Configuration. For information about Licensing Diagnosis, see the topic "Identify Possible Licensing Problems for the RD Session Host Server" in the Remote Desktop Session Host Configuration Help in Windows Server 2008 R2.
