Group Policy Preferences
GP Preferences was released with Windows Vista and Windows Server 2008. It gives much more flexibility in addition to Group Policy Settings (administrative templates), and in some environments it may completely replace logon scripts.
Overview
To work with Windows XP and Windows Server 2003 there must be installed client-side extensions. The most common and practical way to deploy these would be to approve them in WSUS.
If setup and managed from Windows Vista or Windows Server 2008, GP Preferences may also be implemented in a Active Directory domain in Windows Server 2003 mode. This is described in more detail here.
Group Policy preference client-side extension can be downloaded here.
