Event ID 64 — Terminal Services License Server Discovery

Applies To: Windows Server 2008

Terminal Services license server discovery is the process by which a terminal server discovers (contacts) an available license server to request Terminal Services client access licenses (TS CALs) for the clients that are connecting remotely to the terminal server. If the terminal server cannot discover a license server, client connections may fail.

The recommended discovery scope for a license server is forest discovery scope. If you configure forest discovery scope, terminal servers, without any additional configuration, can automatically discover a license server in the same forest, because the license server is published in Active Directory Domain Services. To configure forest discovery scope, you must be logged on as an enterprise administrator to the forest in which the license server is a member.

Note: A terminal server running Windows Server 2008 can only communicate with a license server running Windows Server 2008.
