I found this book to be:
1. A good read. This is oftentimes not a quality on books dealing with computers. Pascal held my attention by focusing on the personalities behind the development of NT, not the technical info. There are many books out there that do that. What he offered was interesting insight into the people behind the product.
2 Well balanced. The technical aspects were simply explained without being condescending or disinteresting. Again, this is a very difficult balancing trick.
As a network administrator and an MCT, I found the background information provided by Pascal both entertaining and useful.
I would recommend this book to any individual seeking to learn more about Windows NT, for whatever reason. I've put it on my recommended reading list for my students
