Query: A classic in the making

This is a great DNS book - to rival the DNS and Bind book by O'Reilly. Like the Bind book, this one gives a basic understanding of how DNS works, but it explains it in terms of Windows 2000 rather than Unix like the O'Reilly book. It gives some great practical examples. I work in customer support, supporting network and system administrators and every customer who calls with a DNS question, I recommend this book.One review in Amazon said it doesn't do a good job of explaining Active Directory - but AD is not in the realm of DNS - you need other sources to see how AD works.
