This thing is gargantuan. It is a whopping 1653 pages of high quality Windows Server R2 information. If this book doesn’t contain the information you need about Windows Server 2008 R2, then you probably won’t find it anywhere. I am not a server guy. I don’t want to be a server guy, nothing against server guys, but I just think it is a full time job. It is not possible for me to keep up with my .NET Software Architecture skills and also be an effective server administrator. Of course I have to be familiar enough with them to architect scalable, secure, high performing software, so I chose this book as my learning resource. It is a great resource. I have not gone too it and come away disappointed yet. The book is broken down into 11 parts: Part I- Windows Server 2008 R2 Overview Part II- Windows Server 2008 R2 Active Directory Part III- Networking Services Part IV- Security Part V- Migrating to Windows Server 2008 R2 Part VI- Windows Server 2008 R2 Administration and Management Part VII- Remote and Mobile Technologies Part VIII- Desktop Administration Part IX- Fault-Tolerance Technologies Part X- Optimizing, Tuning, Debugging, and Problem Solving Part XI- Integrated Windows Application Services Almost every chapter begins with a section that covers the history of the topic, or gives an overview of the topic, included the vocabulary of the topic at hand. The authors writing style makes it an easy to read book, or at least as easy as server reading can get. This book is not like some I have seen that are written by several authors, they usually seem to be very disconnected and you can tell when one author stops and another starts. This book flows nicely from chapter to chapter. If you are in anyway involved with Windows Server 2008 R2, you owe it to yourself to get this book. It will not leave my side!!!!
