Answer: Windows Server 2003 typically creates an application directory partition to hold the DNS information that’s replicated only to domain controllers (DCs) that are DNS hosts. If you upgraded from an earlier version of Windows, this partition might not exist. You can create it by performing these steps:

1. Start the Microsoft Management Console (MMC) DNS snap-in (click Start, select Programs, then click Administrative Tools, DNS).
2. Right-click the DNS server name and select “Create Default Application Directory Partitions.” A window like the figure at Figure appears.
3. Click Yes when asked whether you want to create a single partition for all DNS servers in the domain.

You can also create the DomainDNSZones partition from the command line. To create a partition for only the domain in which the DNS server resides, execute the command

dnscmd <DNS server> /CreateBuiltinDirectoryPartitions /Domain

where <DNS server> is the name of your DNS server. To create a partition for every domain in the forest, execute the command

dnscmd <DNS server> /CreateBuiltinDirectoryPartitions /AllDomains
