This book is very good. It covers, as the title suggests, Networking Foundations. Most of the book is similar to the Windows Server 2003 book by Minasi, however there are sections (which are marked) where Server 2008 new stuff is covered. I've read a lot of server books and most are dry or irrelevant. This book is neither. It has a lot of information that is helpful and even a bit of humour. I'd wholeheartedly recommend this book!
