Written by the husband and wife team of Russel and Crawford, this is not only a complete text on just about everything you can do with XP Professional, but is (for a complex computer book) easy to read.
In addition to the usual here's how to do that instructions that you would expect, this book goes into other aspects of moving to XP Professional like planning the deployment, automating the installation process, and working in a multilingual atmosphere.
As seems to have become Microsoft standard practice, the CD includes a fully searchable eBook of this complete text and a couple of other books. It also has some 120 tools and utilities to assist in the administration of both clients and servers.
This is the third edition of this book, it includes feedback from readers of the first two editions and is updated to include Service Pack 2, the most recent update to XP (at the time of this writing). This update contains major changes to XP, particularily in the area of security. This alone makes previous editions almost useless.
