Author Notes

Author Bio: Upgrading and Repairing Networks, Fourth EditionUpgrading and Repairing Networks, Fourth Edition Author Bio Terry William Ogletree is a consultant currently working in New Jersey. He has worked with networked computer systems since 1980, starting out on Digital Equipment PDP computers and OpenVMS-based VAX systems. He has worked with Unix and TCP/IP since 1985 and has been involved with Windows NT and Windows 2000 since they first appeared, as well as the newest additions to the family, Windows XP and the Windows Server 2003 family of servers. Besides being the lead author of the third edition of this book, he is the author of Windows XP Unleashed, Practical Firewalls, and The Complete Idiot's Guide to Creating Your Own CDs (with co-author Todd Brakke), and he has contributed chapters to many other books published by Que, including Microsoft Windows 2000 Security Handbook and Special Edition Using Unix, Third Edition. He is also the author of Fundamentals of Storage Area Networking. When not writing for Que, he has on occasion contributed articles to PC Magazine. You can email him at t@w2003tech.com or visit his home page at www.w2003tech.com. When between jobs and not writing for Que, he can often be found on street corners holding a sign that reads "Will work for hundreds of thousands of dollars." Thomas Crayner (Chapter 2) currently is the Director of Applications and Infrastructure Services at a leading pharmaceutical company, where his department keeps 300 servers running in support of R&D operations. Starting with Unix and TCP/IP in the mid-1980s as an applications developer, he slowly worked his way into infrastructure development. During the course of his career, Tom has designed and implemented systems and networks of all shapes and sizes. On the weekends, he can still be found enjoying his original hobby: system and application development. Dwight Tolay, Jr. (Chapter 6) started out as a computer test technician in the 1970s. Branching out into the electrical construction industry, he became familiar with data and fiber-optic cabling, has worked with coax Ethernet and IBM Token-Ring, and has followed the evolution up to today's Category 6 and Gigabyte cabling methods. Currently, he is a general supervisor for Ortlip Electric Co. He is a graduate EE, an ISA certified Level III control systems technician, a licensed electrical contractor, and a certified high-voltage test technician. In addition to being a certified fiber-optic and teledata instructor at a local trade school for the past 13 years, he has contributed as technical editor on various books and currently is involved in a book on Home Data and Electrical Systems Integration. Scott and Kalinda Reeves (Chapters 32 and 33) are a married couple who live in Heron, Montana, where they have written several networking exam books. Scott has accrued his certifications as a Master Certified Novell Engineer (MCNE), Microsoft Certified Professional (MCP) in Windows NT, Compaq Accredited Systems Engineer (ASE), Comptia Network+ professional, and Comptia A+ certified technician. He has more than 15 years in the computer industry, and he has worked in the networking field for more than 11 years. Kalinda has more than 16 years' experience writing research, business, technical, and engineering documentation for government, military, and civilian customers. The topics include system- and circuit-level hardware; uniquely developed, hardware-specific programs; and programs that are implemented across government and military communications systems. Kalinda currently works as a freelance writer.
