Data type: REG_WORD

Default: 512

Description: For a directory service acting as a bridgehead server, this key sets the maximum number of directory update objects the directory service can send in one message when it is responding to a directory replication update request message. If the local directory service has more than this number of objects, it tells the remote directory service (by means of a message) to request more objects.

IMPORTANT: Leave this value alone unless you have a specific requirement.
