JSI Tip 8738. Your Windows Server 2003 Terminal Server License server records Event ID 1009 in the System log?

In a Windows Server 2003 domain, your Windows Server 2003 Terminal Server License server records the following in the System event log:

Event Type: Warning
Event Source: TermService
Event Category: None
Event ID: 1009
Computer: <ServerName>
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.

This behavior occurs if the LicensingGracePeriodEnded registry Value Name is NOT set to 0 at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService\Parameters when per User CALs are installed. When set to 0, the event message is suppressed and the Terminal Services license count-down process is terminated.

The easiest way to set to the LicensingGracePeriodEnded Value Name is to open a CMD.EXE prompt and type:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\TermService\Parameters" /V LicensingGracePeriodEnded /T REG_DWORD /D 0 /F

NOTE: See The function of Terminal Server CALs in Windows Server 2003.
