I got this because it was recommended to me. Plus I couldn`t live without Stanek`s Windows Server 2003 Inside Out and he`s a coauthor of this so I was fairly certain it would be worthwhile. Initially, I spent most of my time in the first few chapters as will most admins. The first chapter covers how group policy works with solid depiction of default policy and what it should/shouldn`t be used for. The next chapter drills into everything you need to know about GPO creation, linking, delegation, RSoP, and GPMC. Chapter 3 is where I finally learned how GP processing and refresh work from low to high something even Moskowitz`s book doesn`t do a good job of detailing. There`s also detailed discussion on copy, import, backup, and restore again something not covered well in Moskowitz`s book. Chapter 4 is about deploying Group Policy with design considerations, best practices, and migration details. Chapter 5 is about hardening clients and servers using policy. I would have paid the cover price for these 5 chapters (200+ pages) alone. The rest of the book drills chapter by chapter into nearly every area of policy, policy optimization, policy customization (550+ pages).
