I particularly bought this book for MOM 2005 setup\configuration and found that this book wasn't I expected to be. First, it doesn't go deep in explaining configuration of management packs. Second, it is poorly organized. Author is jumping back and forth between configuration topics and that is very annoying. If your goal is to learn MOM 2005 thoroughly then your money is well spent somewhere else. It is better to read Microsoft documentation on MOM 2005 than this book. The book is simply too small to cover all three topics.
