Yes, u can. By using Active Directory Module with PowerShell Script it may be possible to automate the administrative functions (consider cmdlets). Built-in Windows PowerShell commands,called cmdlets provides the functions what u want. But it needs at least on Windows Server 2008 R2 Domain Controller running Active Directory Web Services (ADWS) in the domain.
OR, alternatively, AD Management Gateway Service can be installed on Windows Server 2008 server with or without SP2 installed. It makes able to do scripting even remotely from server computer, or other workstation. And of course it does require Windows 7 in order to install the Remote Server Administration Tool.
One more info is in SP 1 there is a new feature called RemoteFX. It is an improvement that should help to using Microsoft Remote Desktop Services on thin clients.
