If you like the Remote Desktops snap-in and are running Window 7 you will need to download the Remote Server Administration Tools for Windows 7 from http://www.microsoft.com/downloads/en/details.aspx?FamilyID=7d2f6ad7-656b-4313-a005-4e344e43997d&displaylang=en.
After it has been installed you can turn the feature on.
