I have used ISA Server 2006 since 2006 and thought implementing a 2 server TMG enterprise array would be no problem. After some issues, I bought the book and had it delievered the next day. The book was very helpful, especially in its content about planning properly and various network design considerations. I was able to correct many issues and get my system operational much quicker. The TMG is complicated, so chasing symptoms can be time consuming.



Especially helpful are the "Real World" sections scattered throughout the book. These show actual TMG problems resolved and their underlying causes. For example, I was having a problem with IP Spoofing. Pp. 596-7 describe the problem in detail and how to resolve it. Another nice feature is chapter 33 on using Network Monitor 3 for Troubleshooting TMG.



While Microsoft Technet and the TMG built in help are somewhat helpful, I needed to know the how and why of the systems features. The authors' explanation of network protocols in conjunctin with TMG also help.



I recommend this book for any person planning to implement TMG. The book will help you plan properly and get the most out of the system. It is also helpful for troubleshooting.
