This is the book we are using in my curent class at school. It's the first class of the second wheel and is now teaching more advanced techniques from what we learned in the past six months. This book is from "Thomson Course Technology" I have read two other books from this company and both were pretty good. While the techniques in this book have been a bit confusing for me, such as cryptology and certificate authorities, none the less this as an excellent book.
Authors: Will Schmied - Robert J. Shimonski - Nicholas Wells

While the book can be somewhat vauge I would reccomend it for anyone looking to expand upon their basic Windows 2000 security procedures.
