Poorly written and way out of context. My advice to anyone wishing to learn the real ins and outs of 2003 server would be to buy Mark Minasi's book - he offers much better advice geared towards the real world and his chapter on DNS is far superior to the drivel written in this publication.
I particuarly dislike the monotonous tone that so often is the down fall of Microsoft publications.
On the upside - this book is given it's blessing by *Microsoft* - so it must have something going for it. The section on Group Policy is not bad.
However - just go to Borders and compare the difference - Minasi's book on 2003 server is *the* bible to have with regards to decent technical writing and explanantions of real world situatios with regards to 2003 server.
