The Preferred DC Active Directory Provider namespace executes Active Directory operations so that they bind to a specified domain controller (DC). Each procedure in the Preferred DC Active Directory Provider namespace calls the corresponding procedure in the Active Directory Provider namespace. Each procedure of the Preferred DC Active Directory Provider namespace also includes a call to the Make Path Domain Controller Specific procedure, which passes the preferred domain controller as a parameter.
This namespace is useful when you must execute a transaction that performs multiple operations on an Active Directory object. Using a single preferred domain controller eliminates replication delays that arise between multiple controllers. It is also useful if a transaction provisions another service that uses Active Directory, and you know which domain controller it is most likely to use. For example, if the other service is Microsoft Exchange 2000 Enterprise Server and the Exchange server is in a particular Active Directory site, the domain controller for the Exchange server should be the preferred domain controller.
Preferred DC Active Directory Provider is a wrapper for procedures in Active Directory Provider, and is implemented as Program Files\Microsoft Provisioning\Providers\MPFADProv.dll
The XML schemas for requests are a combination of the elements in the Make Path Domain Controller Specific procedure and one of the Active Directory Provider namespace procedures referenced below.
