Query: Excellent study guide in desperate need of proofreading.

I am beginning to believe that any book with "MCSE" in the title was written with a "damn the proofreading, full speed ahead, get those training bucks before someone else does" attitude, and this one is no exception. In spite of the abundance of errors, the book is well organized and is an excellent study guide for someone preparing for the Microsoft TCP/IP exam. However, you'd best have reliable reference sources (e.g., Comer's vol. 1, Albitz & Liu's DNS & BIND, Technet, the lab setup itself) to resolve the many suspect things in the book; using those references and otherwise following this book's course of study, with the labs, will prepare you well for the exam. Once you've passed the exam, however, this book is of little value as a future reference.
