The ADMG or
Active Directory Management Gateway Service or Active Directory Web Service
for Windows Server 2003 and Windows Server 2008 has RTMed !
I posted before about this component that enables you to use the
Powershell 2.0 AD Module to manage your Active Directories.
So now not only on 2008 R2 but also on 2003,2003R2 and Windows 2008 Server (in RTM version this time)
