The first two editions of this book were called DNS on Windows NT and DNS on Windows 2000, and they dealt with Microsoft's DNS implementation for those operating systems. This new edition has been updated to document the many changes to DNS, large and small, found in Windows Server 2003. In particular, this edition documents use of the dnscmd program to manage the Microsoft DNS Server from the command line and development using the WMI DNS provider to manage the name server programmatically. The book also covers new features of the Microsoft DNS Server in Windows Server 2003, including conditional forwarding and zone storage in Active Directory (AD) application partitions.
