Terminal Server License Server/Remote Desktop License Server Only Issuing Temporary Licenses and Event ID 17 Logged


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.

Event Type: Warning

Event Category: None
Event ID: 17

One or more Terminal Server Licensing certificates on server LS01 are corrupt. Terminal Server Licensing will only issue temporary licenses until the server is reactivated. See Terminal Server Licensing help topic for more information.

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.

Windows Server 2008 R2 Activate Server wizard

The RD License Manager encountered an internal error from the license server. Message Number: 0xc0110011

Windows Server 2008 and Windows Server 2003 Activate Server wizard

The License Server Activation Wizard encountered an internal error from the license server
Message Number: 0xc0110011

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.

Can't generate a license for client because of error 'Can't add certificate to store, error c0010020.'

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.
