The chapter assessments have exhibits which aren't clear enough to answer the questions without taking a leap of faith, and some of the answers are ambiguous at best (like leaving the word "deny" out of "deny packet filter"). This is not very helpful to people who are novices with the product.

If you are hoping to use the CD to cement your knowledge, forget it. While the questions may well be valid, they are poorly presented and the questions and answers wrap off the screen on some systems. Mine even told me I was doing an Exchange exam at one stage. This is simply not what you expect from a major publisher - if you're going to include this quality of material, you shouldn't bother bundling it at all.

If you bought this book already, consider getting a transcender test to test and rebuild your knowledge, and play with an ISA server - the online help contains a wealth of information about it. Also be aware the book went to press before FP1 was released, so there is nothing about the OWA publishing wizard.

This will probably be the last Sybex book I buy. I have been unimpressed by several of their titles now - so I'll be sticking to the genuine Microsoft material in future!
