Event ID 80 — Terminal Services Client Access License (TS CAL) Availability

  • Article

Applies To: Windows Server 2008

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

TS CALs are installed onto a license server by using the TS Licensing Manager tool.

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