In a Microsoft Windows Server 2003-based domain, the following Windows event is logged in the System log on the Terminal Server or on the Terminal Services License server:
Event Type: Warning Event Source: TermService Event Category: None Event ID: 1009 Computer: Server Name Description: The terminal server licensing grace period is about to expire on date and the service has not registered with a license server with installed licenses. A terminal services license server is required for continuous operation. A terminal server can operate without a license server for 120 days after initial start up.
Note If this event is logged on the Terminal Server, you must make the registry changes on the Terminal Server. If this event is logged on the Terminal Services Licensing Server, you must make changes on the licensing server.
This symptom occurs if the following conditions are true:
The Windows Server 2003-based domain has Windows Server 2003 Terminal Server License servers with Terminal Services Per User Client Access License (CAL) tokens installed.
The Windows Server 2003-based domain has Windows Server 2003 Terminal Services servers running in Per User mode.
This issue occurs if the LicensingGracePeriodEnded registry entry is not set. The LicensingGracePeriodEnded registry entry suppresses the event messages that appear in the System log and ends the Terminal Services license count-down process.
