Your Terminal Server license server or Remote Desktop license server issues only temporary client access licenses (CALs). Event 17 is logged in the System log when the Terminal Services Licensing/Remote Desktop Licensing service is restarted or when the computer is restarted. The event continues to be logged even after you try to reactivate the license server.
After you start receiving Event ID 17, any interaction with the Microsoft Clearinghouse except for reactivation generates the following error message, as specific to the system.

Additionally, the license server is deactivated. Deactivation occurs only on license servers that are connected to the Internet and that have the connection method set to Automatic. After the license server becomes deactivated, Event ID 38 is also logged.
This issue affects Windows Server 2008 R2, Windows Server 2008, and Windows Server 2003 license servers that were activated by using the Automatic connection method.
This issue occurs because a certificate that is part of the digital certificate chain expires.
When a TS Licensing server or an RD Licensing server is activated by using the automatic connection method, Microsoft Clearinghouse sends the server a digital certificate chain that validates the ownership and identity of the server. On February 26, 2010, a certificate that was part of this digital certificate chain expired. However, the TS Licensing server or the RD Licensing server interprets the expired certificate as a corrupted certificate. Therefore, an instance of the event that has Event ID 17 is logged.
To resolve this problem, apply the hotfix that is discussed in the following Microsoft Knowledge Base article:
