I bought this book (rather skimpy size) and win2000 clustering (bigger) book to try and tackle several clusters I am to build in 2003 EE. Thanks GOD I bought the 2000 book also. Much of the usable information came from the 2000 book, not the 2003 book. The 2000 book goes right at 2000 clusters, and covers them in detail. This 2003 cluster book spends half the paper rehashing 2000 clusters and then begins showing some of the differences in 2003. Half of the smaller 2003 book is about 2000 clusters. If you do not read the whole book, in order, you cannot build a cluster in 2003. 2003 clustering seems more like an afterthought than the main concern. I also am trying to build IIS6 failover clusters. This book mentions IIS clusters, not at all, nowhere. In 2000 clusters, IIS is a checkoff. In 2003 there is nary any clear documentation on it anywhere, especially this book. While SQL seems to be covered in the 2003 book there seems to be an absence of other program types.
This book lacks any detail on many subjects and omits critical ones entirely.
If you want a technical reference, how to book, this is not it.
Shame. Its currently the only one out there for 2003 clusters.
