Let me tell you about my personal experience...
I was first using this book in collegue.95% of us didnt get it..Even the teacher was kind of clueless..I decided to study it after I finish school. I did and I find out that there were 15 pages of errata from the author..Way too much and big mistakes from the publishers as well..\
To make everything worst..I found out way more than that on my own!
How can a reader say it's an excellent book, when it's pack of sensitive mistakes?
To make everything more interesting , now it's the release of server R2, , way different commands from plain different server 2008, because a lot of the older commands are deprecated ( useless).
Conclusion: i have to study with this faulty guide, I bought the other Microsoft original book, I am using google and you tube like crazy to understand this book, I am reading the errata by my side, and trying to fix the mistakes he didnt post in his errata,( yes, making an errata for the errata!), a lot of the labs are unconclusive because of that, etc., etc..And I am consider my self a good and logical student.
This book mess up my life because after I got into the job market I understood that networking in servers 2008 was WAY too important..When you study from this book, really got me irritated , over and over..
This way slow down my insertion in the job market.And I am a system engineer already..
I understood that the author had good intensions when he wrote this book,and some of the ideas are organize and explain in plain words, but not properly giving a review , publish it packed with errors, and having a lot of people confuse! That's a killer ! C'mom!
