1) The authors failed to acknowledge the different versions of Windows (Win95/98 & NT) which can have quite different setups.2) There is no such thing as "Linux has built-in stability and security..."3) Linux is not "only" a server OS, we use it on desktop everyday.4) ...just because computers are connected by a LAN does not classifies it as an "intranet"5) TCP/IP is NOT the most common method to network PCs on a LAN -- Ethernet is.The publisher claims "guarantee" on their technical accuracy. If this is the best they can do, I'll be very careful buying another Coriolis's book. The authors failed to understand what an intranet server really does, the book title is misleading.Pros: earn 1 star for pretty pictures, but if you are serious about learning Linux this book "won't" give you a good start.
