Event ID 91 — 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.

|Message:||The migration of Remote Desktop Services client access licenses (RDS CALs) has completed. Because the source Remote Desktop license server %1!s! is running an operating system that does not support the deletion of RDS CALs, ensure that %1!s! is no longer used as a license server with the same RDS CALs that were migrated.|
This is a normal condition. No further action is required.
