Moving AD-Integrated Zones into an Application Partition
You want to move AD-integrated zones into an application partition.
Using a graphical user interface
Using a command-line interface

At the time of publication of this book, the DNS WMI Provider did not support programmatically moving a zone into an application partition.
With Windows 2000 Active Directory, if you had AD-integrated zones, those zones were replicated to every domain controller in the domain where they were stored. In many cases, not every domain controller also served as a DNS server, which resulted in increased and unnecessary traffic to replicate zone changes to DCs that did not require the data.
Windows Server 2003 provides an elegant solution to this issue by using application partitions. Application partitions are user-defined partitions that can be configured to replicate with any domain controller in a forest. This provides a lot more flexibility for how you store and replicate your AD-integrated zones. You could, in fact, have a few domain controllers from each domain act as DNS servers for all of your AD domains.
