I bought the book and I still don't have a home network. Need I say more?
If you have 2 or more Windows XP machines there is a wizard provided by XP to setup your network. For reasons I still do not understand this has not worked for me, and the book provides no "insude information" or troubleshooting tactics.
Unfortunately this is a Microsoft publication and is written from the perspective that the Microsoft tool provided works. I guess this is great if it does work, but it didn't for me and the book is certainly not helping in trying to track down the problem.
At least half the book is dedicated to "things to do on your network" - security, resource sharing and collaborative tools and methods. This might be excellent but I haven't got that far yet!
