When trying to use Remote Desktop to connect to a Vista or Windows 7 PC with a 2003 domain account the user needs to be added toRemote Desktop Users Group which works ok until the next reboot.On the subsequent reboot the user is not allowed to login.When connecting using an Adminstrator account to check the problem the Domain user has disappeared from the Remote Desktops User Account.If the user is re added it woirks again until restarting.The user needs to be a non administrator on the remote PC.Another domain user which is a local administrator on the Remote PC and is also in the Remote Desktop Users Group does not disappear from the group on reboot.There are group policies on the domain but nothing specific to Remote Desktop.
