Having learned SMS through a combination of blood sweat and tears and read some appalling SMS 2.0 books, I was nervous at first this book would be of the same standard.
The content is clearly laid out and well thought out. The quality of content is excellent and doesn't always follow the Microsoft lab mentality and sometimes provides real world examples.
However, as the title suggests, this is an "administrators companion" and is not the best book to buy if you want to do the MCSE exam or need the detail of the resource kit.
