I dedicate this book to my father, who was a role model of the value of hard work, commitment to family, and the importance of doing the right thing. Rest in peace, Dad.
—Mike Chapple

This book is dedicated to Ric Williams, my friend, mentor, and partner in crime through my first forays into the commercial IT world. Thanks for making my job as a “network janitor” one of the best experiences of my life.
—David Seidl


Books like this involve work from many people, and as authors, we truly appreciate the hard work and dedication that the team at Wiley shows. We would especially like to thank senior acquisitions editor Kenyon Brown. We have worked with Ken on multiple projects and consistently enjoy our work with him.

We also greatly appreciated the editing and production team for the book, including David Clark, our developmental editor, who brought years of experience and great talent to the project, Robin Abernathy, our technical editor, who provided insightful advice and gave wonderful feedback throughout the book, and Becca Anderson, our production editor, who guided us through layouts, formatting, and final cleanup to produce a great book. We would also like to thank the many behind-the-scenes contributors, including the graphics, production, and technical teams who make the book and companion materials into a finished product.

Our agent, Carole Jelen of Waterside Productions, continues to provide us with wonderful opportunities, advice, and assistance throughout our writing careers.

Finally, we would like to thank our families and significant others who support us through the late evenings, busy weekends, and long hours that a book like this requires to write, edit, and get to press.
