If you must demote a domain controller, consider the following:
If a domain controller holds a replica of an Windows XP exam application directoiy partition, then you must remove the domain controller from the replica set of the application directory partition or delete the application directoiy partition before you can demote the domain controller.
If a domain controller holds the last replica of an application directory partition,then before you can demote the domain controller you must do one of the following: specify that you want the Active Directory Installation Wizard to remove all replicas from the domain controller, remove the replica manually by using the utility provided by the application that installed it, or remove the replica manually by using the Ntdsutil command.
Before deleting the application directory partition, you must:
Identify the applications that use it Determine if it is safe to delete the last replica Removing the last replica of an application directory partition results in the permanent loss of any data contained in the partition. ...
... If you have identified the applications using the application
directory partition, consult the documentation provided with those applications to determine if there is any reason to keep the data. If the applications that use the application directory partition are out of service, it is probably safe to remove the partition. If it is not safe to delete the last replica, or if you cannot determine whether or not it is safe, and you must demote the MCP certification domain controller holding the last replica of a particular application directory partition, follow these steps: Add a replica of the partition on another domain controller, force the replication of the contents of the application directory partition to the domain controller holding the new replica, and then remove the replica of the partition on the domain controller to be demoted.
Application Directory Partition Replication
The KCC automatically generates and maintains the replication topology for all appli-cation directory partitions in the enterprise. When an application directory partition has replicas in more than one site, those replicas follow the same intersite replication schedule as the domain directory partition. Objects stored in an application directory partition are never replicated to the global catalog as read-only replicas. Any domain controller running Windows Server 2003 can hold a replica, including domain controllers that also act as global catalog servers.
In addition, if an application requests data through the global catalog port (with LDAP, port 3268, or with LDAP/SSL port 3269), that query will not return any objects from an application directory partition, even if the computer hosting the application directory partition is also hosting the global catalog. This is done so that LDAP queries to different global catalogs will not return inconsistent results because the application directory partition is
free practice tests replicated to only one of the servers hosting the global catalogs.
