Understand the licensing grace period

Published: November 11, 2011

Updated: November 14, 2011

Applies To: Windows Server 2003, Windows Server 2008, Windows Server 2008 R2

The grace period begins the first time the terminal server (Windows Server 2008 or Windows Server 2003) or the RD Session Host server (Windows Server 2008 R2) accepts a client connection.

The grace period ends when either of the following conditions is met:

  • A permanent Terminal Services client access license (TS CAL) is issued by a license server to a client connecting to the terminal server (Windows Server 2008 or Windows Server 2003), or a permanent Remote Desktop Services client access license (RDS CAL) is issued by a license server to a client connecting to the RD Session Host server (Windows Server 2008 R2).

  • The number of days in the grace period is exceeded.

After the terminal server receives a TS CAL, or an RD Session Host server receives an RDS CAL, we create LicensingGracePeriodEnded under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService\Parameters.

When we are nearing the end of the grace period, we log an event to let users know that the grace period is about to expire.
