If you haven't thought about the technical aspects of Active Directory
in depth for a little while, this will be a great refresher.
Active Directory (AD) is one of the most complicated aspects of Windows
2000 and Windows Server 2003, and most of us don't have the time to look
through tons of books to find the basic technical details needed to
manage AD properly. Therefore, I hope this series of articles will be
beneficial to those busy system administrators and AD architects out
there who've let some of the basic concepts of AD slip their mind.
