If you are installing the CTP of April of Longhorn you may wonder where the gpmc.msc console is. Simple , it´s  not there, you will have to install Group Policy Management Console with Service Pack 1 (doesnt work on x64 systems and .net is needed) or solve it as I did, by running the gpmc.msc on your domain joined vista client.
 Happy Easter
