About the Author

Craig Zacker got his first experience with computers in high school on a minicomputer "with less memory than I now have in my wristwatch." His first networking responsibility was a NetWare 2.15 server and six 286 workstations which eventually evolved into NetWare 4 and over 100, plus WAN connections to remote offices. He's done PC and network support onsite, in the field and over the phone for more than five years, and now works for a large manufacturer of networking software on the east coast, as a technical editor and online services engineer.

Paul Doyle has several years of experience in the planning, implementation and management of networks in multi-protocol, multi-vendor environments. His specialist areas include client configuration and server management.

Christa Anderson started working with computers in the 1980ís, long before anyone let it slip to her that you could make a living with them. Since 1992, she has written on such subjects as PC troubleshooting, data communications, and PC security, with her current interests centered on local and wide-area networking issues. Previously a member of a cutting-edge consulting team in the Washington, DC area, since her move to a city with better parking, she is now an independent technical writer and researcher.

Darren Mar-Elia graduated from the University of California, Berkeley in 1986. He has been a network and systems administrator for the last 10 years. He is a Novell CNE, and has been involved in design and installation of heterogeneous LAN/WAN environments for large and small companies alike. Most recently, he was part of the design team for a nationwide deployment of Windows NT at a large financial services firm, and is currently part of that firmís network engineering group.

Alexia Prendergast is an information developer who has been writing and designing user manuals, system administration guides, and courseware for five years. Her experience includes documenting client/server business applications in the healthcare industry, application development software systems in the banking industry, and three-tiered automated manufacturing systems in the steel and metals industry. Alexia has worked with a variety of platforms, including UNIX client/server networks, corporate mainframes, and PC and Macintosh desktops. When not working, she can be found designing web pages and surfing the net, doing genealogical research and spending quality time with her partner and their four animals.

With a Bachelor's Degree in Spanish and Russian, and a Master's Degree in Information Science, both from the University of Pittsburgh, Michele Petrovsky has over 15 years in data processing. In 1990, she moved from programming and system administration to freelance technical editing and writing in a number of environments, and teaching at the community college level. Michele lives on a farm near Wilmington, Delaware. Her outside interests include Star Trek and science fiction in general, cats, gardening, and linguistics. She dedicates her work on this book to her parents Mike and Betty, and welcomes reader comments and inquiries at mpetrovsky@aol.com.

Paul Robichaux, who has been an Internet user since 1986 and a software developer since 1983, is currently a software consultant for Intergraph Corporation, where he writes Windows NT and Windows 95 applications. In his spare time, he writes books and Macintosh applications; he still manages to spend plenty of time with his wife and young son and.He can be reached via e-mail at perobich@ingr.com.

Acknowledgments

Without the help of some terrific people my contribution to this book would nver have happened. Nancy Stevenson put me in touch with Fred Slone at Que, Fred gave me lots of support and encouragement, Scott Anderson provided moral support and shoulder rubs, and Mark Minasi showed me that you really can make a living at this stuff. My special thanks to all those who helped me research my contributions, particularly Geoff Milner, Curtis Taylor, Glenn Stern, and Michael Willett. Finally, I really appreciate the efforts of the editorial and production staff at Que, whoíve worked to make this book such a good one.

--Christa Anderson

I wish to record my gratitude to my family for their patience and indulgence while I worked on this book. Without their support, I would have been unable to undertake a project of this scale.

Thanks also to Fred Slone for the opportunity to work on this project and for an impressive display of patience and encouragement.

My thanks to my colleagues in UCG for their words of wisdom and unstintingly high standard of comradeship. Thanks also to those less proximate colleagues who share their ideas, questions and other work on the Internet.

Oh, and I promised Pat Rooney a mention.

--Paul Doyle
