Locating an Application Directory Partition Host Server

The NetLogon service registers the following list of SRV records for an application directory partition:

_ldap._tcp.<partition name>.
_ldap._tcp.<site name>._sites.<partition name>.

To locate a domain controller that hosts a replica of a specified application directory partition, call the DsGetDcName function with the DomainName parameter set to the DNS name of the application directory partition and the DS_ONLY_LDAP_NEEDED flag set in the Flags parameter. For more information and a code example that shows, using the DsGetDcName function to locate a domain controller that hosts a replica of an application directory partition, see Example Code for Locating an Application Directory Partition Host Server.
