Last Week I got a complimentary copy of Joe Richards and Robbie Allens new release of "Active Directory". Among others I was technically reviewing this book, and honestly I was looking forward to the book in the stores. They've done a great job: the 3rd edition of the book is even valuable for people who already got the 2nd edition. They've added a lot of content, three new chapters, cover ADAM, WS2k3 SP1, R2, and as always a lot of background information plus scripting samples. There are not that many books about AD I'd recommend, but this one definitely.
Footnote: No - I did not receive any money reviewing this book or writing in here about it. I wanted it to become even better, and I'm writing about my opinion here. This is not a advertising, just a comment what I like.
