This update resolves the "Terminal Services OEM License Server Activation Failure" issue that occurs only on servers that are obtained through Microsoft Original Equipment Manufacturers (OEMs) or System Builders and are configured with the Terminal Services Licensing service. For these specific servers, the Windows 2000 Terminal Services license server activation does not verify the activation certificate obtained from the Microsoft Clearinghouse. This results in a failure to activate the server as a Terminal Services license server. As a result, Windows 2000 Terminal Services Client Access licenses cannot be installed.
