O'reilly does a wonderful job writing books in a logical well organized manner.
For a first edition I was hard pressed to find many obvious mistakes. They did their due diligence.
This book is written for the IT PRO, not someone looking to learn Active Directory or other services in Windows Server 2008 hoping to pass a paper cert test. It's assumed you have a broad understanding of Microsoft's culture and product lines and are looking for a practical review of technologies in 2008.
You don't have to be a AD guru to get a lot out of this book either. I would actually recommend it above Microsoft Press books, because instead of trying to indoctrinate you on a set of "standards" Hassell simply gives you a working set of parts under the hood. He doesn't get caught up on the politics or test taking.
I do not recommend this book as a project management guide to upgrading from 2003 to 2008. This isn't one of "those" books. Instead, it's a good book for someone exploring the idea and reasons for upgrading, by being exposed to what is inside 2008 Server first.
As with almost any O'Reilly book, I think this is a definite buy for your IT library. It's well priced too.
