Query: Must have for anyone working with AD

A must have book for dealing with AD. I primarily bought book for some scripting help with AD, however, after seeing book, it's great whether you are using Command Line, GUI, VB, or Perl (from web site). The discussion after each topic is also very informative. So no matter what method you are using, this book will describe how to do it.
