Paul Thurrott has published "Windows Server 2003: The Road To Gold Part Three: Testing Windows" at Winsupersite. In the whole series Paul has tried to give a insiders view of "How MS churns-out OS in Redmond" . Its a very interesting read for anyone and particularly for people using Windows Xp and Windows Server 2003. And also Paul is going to publish "Windows Server 2003: Part four :The Road to Gold".
