I am a programmer for a small software company. Besides programming, I also do training and I fly places and install client/server database engines (and our app) on various networks; which means that I end up troubleshooting misconfigured networks. We have tech support people who talk to IS people at different companies every day. I have recommended to my boss that he buy a copy of this book for every one of our techs. This book uses clear language and covers all the relevant subjects. It is well-organized and almost free of errors. Kudos to Lisa Donald!This book is destined to be a classic.Who's saying this? A guy who's an MCSD and a Sun Certified Java Programmer.
