AD Removing Lingering Objects
repadmin /removelingeringobjects DCSERVERNAME GUID of good working DC dc=xxxx,dc=xxxx
The repadmin /removelingeringobjects command does the following:
Compares
the directory database objects on a reference domain controller with
the objects on the target domain controller, which contains (or is
suspected to contain) lingering objects.
Either removes the
lingering objects or logs the potential deletions to the Directory
Service event log, as follows:
• If you use the /advisory_mode parameter, events are logged in the Directory Service event log for the objects that are found.
• If you do not use the /advisory_mode parameter, the found objects are deleted without replicating the deletions; that is, the deletions occur only on the target domain controller.
