The authors of this book obviously know their stuff, but are unable to pass it on. The book is a list of what is available from Microsoft and step-by-step how to implement it in a patronizing "Click Start" kind of way. However, it fails to give the reasons why features are implemented in such and such a way. Instead of giving the threat and telling us how Microsoft deals with it in their products, the authors drone on about what all the options for X do. In short one cannot try and read this cover-to-cover, it is quite handy as a reference but I'm sure the on-line references are sufficient for this kind of stuff.
