Active Directory Lost and Found Test

On a domain controller, the Lost and Found container contains Active Directory objects that have been orphaned. An object is orphaned when the object is created on one domain controller and the container in which the object is placed is deleted from the directory on another domain controller before the object has a chance to replicate. An orphaned object is automatically placed in the Lost and Found container where it can be found by an administrator.

This test reports the number of orphaned objects currently in the Lost and Found container, provides the details of these objects, so that administrators can determine which objects to move and which ones to delete.
