Removes lingering objects - an object stored in Active Directory that has
seen, deleted and garbage collected by a reference DC but continues to
incorrectly exist on direct or transitive replication partners DC's that
have not inbound replicated knowledge of the objects deletion within
tombstone lifetime number of days.
The PC running repadmin may have Windows Vista or Windows Server 2008
installed, and must have network connectivity to all domain controllers
targeted by the parameter.
The reference DC must host a writeable copy of the directory partition
targeted for lingering object removal and have network connectivity to all
domain controllers targeted by the parameter.
DC's targeted by the parameter may host read-only or writeable
copies of directory partition targeted for lingering object removal.
DC's and Global catalogs targeted by continue to advertise
and service ldap request during lingering object removal.
The reference DC and domain controllers targeted by the
parameter may have Windows Server 2003, Windows Server 2003 R2 or
Windows Server 2008 installed.
There are no domain or forest functional requirements for this command.
ADVISORY_MODE is a test mode that logs NTDS Replication events 1938, 1946
and 1942 in the targeted domain controllers' directory service event log
identifying the lingering objects that should be removed but does not
actually remove them.
Lingering objects are removed when "repadmin /removelingeringobjects" is
run without the /advisory_mode switch. NTDS Replication events 1937, 1945
and 1939 logged on the target DC's directory services event log identify
the start, conclusion and set of objects removed from a directory
partition.
You should conceptually think of DC's in the as the "bad" DC's
that you want to test or remove lingering objects from and
as the "reference" DC.
Microsoft recommends enabling strict replication consistency before
removing lingering objects.

[EXAMPLES]
The following command would check the Europe NC on all DC's in the site HQ
for lingering objects using the DC specified by its ObjectGUID
667f7037-8198-4357-8f15-8f709f04b6e2 as reference.
The /ADVISORY_MODE will cause events to be written to the Directory Service
Event Log for each of the target DC's indicating how many lingering objects
were found.
