Event ID 80 — Remote Desktop Services Client Access License (RDS CAL) Availability

Applies To: Windows Server 2008 R2

When a client—either a user or a device—connects to a Remote Destkop Session Host server, the RD Session Host server determines if a Remote Desktop Services client access license (RDS CAL) is needed. The RD Session Host server then requests an RDS CAL from a Remote Desktop license server on behalf of the client attempting to connect to the RD Session Host server. If an appropriate RDS CAL is available from a license server, the RDS CAL is issued to the client, and the client will be able to connect to the RD Session Host server.

RDS CALs are installed onto a license server by using the Remote Desktop Licensing Manager tool.
