The information in this book is well laid out and the explanations of many topics are very good. However, the book has many problems that keep me from recommending it to anyone. First of all, I think it doesn't have enough detail. Unless you are already familiar with the topics (and in that case, why are you reading this book?), you might have a hard time understanding some of the explanations. For example, the very brief explanation of disk suballocation could only be meaningful to someone already pretty familiar with that topic. In addition, there isn't enough detail to help you with some of the test questions! Ugh. I think there is enough to pass if you review the book carefully and combine it with other books and resources. Next, there are way too many errors in this book. The author and editors should be embarrassed. I know I would be embarrassed to have my name on anything with so many glaring and confusing mistakes. For example, the two-page example of file security, which is supposed to help summarize and clarify the chapter, is totally wrong. You can see in part of the example the rights "flowing down" or being inherited, as they should be, and in the piece of the example next to it, where nothing is different, the rights are not being inherited. Many of the end-of-the-chapter review questions have the wrong answers and explanations. Some chapters have contradictory, wrong, or vague information. In some places, the book unexpected changes terms and starts using the wrong terminology...as if the person who typed the book up was confused. I found myself constantly turning to other NetWare 5 reference books and Novell's webpage to figure out where the book was wrong or to clarify vague points. In the end, I felt like I couldn't trust the information in it. I threw it away right after taking the test--because of all of the errors, it is not very helpful as a reference and I wouldn't want to give it to someone else to use. I still give the book two stars, because if you combine it with another, better book, use other sources, and are already somewhat familiar with NetWare, you could find the book helpful.
