Starting with Windows Server 2003 SP1, it is possible to provide server authentication by issuing a Secure Sockets Layer (SSL) certificate to the Remote Desktop server. This is easy to configure using the “Remote Desktop Session Host Configuration” tool on Server operating systems. Though no such tool is available on Client operating systems such as Windows Vista and Windows 7, it is still possible to provide them with certificates for Remote Desktop connections. There are two possible ways to accomplish this. The first method is using Group Policy and Certificate Templates, and the second one is using a WMI script.
