P. 394, paragraph just before The "Do Nothing" Approach header: The last sentence is missing a close parentheses after "Exclusive to the Computer Node".
P. 394 states that "Windows 2003 client computers do not ever cache files; this feature is specifically disabled in the operating system." It's not quite true that they never cache files, and for example, p. 402 even says "If you intend to use Offline Files when logged on to Windows 2003, you must disable Remote Desktops". Also, p. 418 says "You can use the Allow or Disallow use of the offline files feature policy setting to your advantage to turn on Offline Files on all your Windows 2000 Servers or Windows Server 203 computers".
P. 404: The first paragraph refers twice to "co-interdependent processes". I assume "interdependent" is meant (co-interdependent being presumably redundant).
P. 419: "There appears to be no way to allow the caching of the hard-coded database files listed earlier". However you can enable caching of these file types (.MDB, .PST, etc.) by removing them from the list in the GPO setting. That doesn't necessarily mean it's a good idea (I've had lots of issues experimenting with caching PST files for example), but it is possible.
P. 420, next to last paragraph: "You can configure a GPO to stop block offline caching..."
