Hello Networking readers!

So recently I have been doing the Network Administration II classes and I have noticed that the book handed out to students has a LOT of errors, not only in the review questions but in the book itself.

The book that I am talking about is the MCTS Guide to Microsoft Windows Server 2008 Network Infrastructure Configuration Exam #70-642

I will be posting the answers to the review questions for this for as many chapters as I can (or if anyone has a chapter review they want to see, let me know)

Also, I'll put up an 'average' midterm Q&A, about 100 questions from the databank for studying up on this exam.

Thanks much and stay tuned for more very soon!
