After you bring back online a domain controller or global catalog server that has been offline for a long time, any of the following problems may occur:
A domain controller (which may also be a global catalog server) that was offline for longer than the value of the Tombstone Lifetime setting (the default value is 60 days) may contain objects that have been deleted on other domain controllers or global catalog servers. Additionally, tombstones for these objects may no longer exist. When you bring the outdated domain controller back online, it cannot be notified of the object deletions. If any of the objects are modified, they are reactivated in the rest of the domain.
For lingering objects that replicate into read/write naming contexts, the standard behavior (Loose Replication Consistency) is for the receiving domain controller to re-create the objects that are not already present in the local database (DIT). These objects are then replicated back to the originating domain controller, effectively re-creating the deleted objects. If the object should not exist in Active Directory at all (for example, if the object was reintroduced by an outdated domain controller), you can delete the objects with the standard tools (such as ADSIEdit or the Active Directory Users and Computers snap-in).
It is easy to remove lingering objects for read/write naming contexts. This article describes how to remove lingering objects that have already appeared in global catalog (and therefore read-only) naming contexts.

(http://support.microsoft.com/kb/326797/ )Some Windows 2000 Active Directory hotfixes may cause a conflict with S326797 for Windows 2000
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows 2000 Service Pack 3.
This hotfix adds support for removing lingering objects. This procedure requires the objectGUID of a domain controller that has a read/write copy of the object, and the objectGUID of the object itself. If you must remove more than one object, determine whether any of the objects are in a parent/child relationship (you can determine this from the objects' distinguished names). If this is the case, order the deletions so that all of the child objects are deleted before their parent objects.
The best way to identify in which domain an object is located (and from that to determine the name of a domain controller that has a read/write copy of the object) is to establish the distinguished name of the object. You can do this by searching for the name (or parts of the name) of the duplicate user, group, or distribution list by using the Ldp.exe tool from the Support Tools:
Run the repadmin /showreps dc-name command (where dc-name is the name of the domain controller you located). Repadmin.exe is included with the Support Tools. From the output, note the domain controller's objectGuid:
C:\>repadmin /showreps some-DCInstall the hotfix that is described in this article on all of the global catalog servers that have lingering objects. The hotfix is not required on domain controllers that you identify as containing read/write copies of the lingering objects, unless they are also global catalog servers that contain lingering objects. Each global catalog server on which you intend to run the delete operation must have network connectivity to the domain controller that you identified.
DSA Options : (none)
objectGuid : d1fa2207-ae85-466f-88fd-908f1c623ea7
For few objectsIf you have only a few objects and global catalogs, follow these steps to delete the objects by using Ldp.exe:
For many objectsIf you have many objects to delete and many global catalog servers, it may be easier to use the following scripts:
Error message when running Walkservers.cmd to modify many lingering objects in the environment
Object <GUID=ae856ce5-839a-4e44-b2fb-f37082ca2555> : <GUID=514f7510-451a-4297-8129-9b4c8ab79axx> could not be removed. Error number is: -2147016672. Error description is: .
CauseThis error occurs because the script is run against the GUID of a domain controller that does not contain a writeable partition that contains the lingering object. Verify the location of lingering object by the Ldp.exe tool.
ExampleIn the following example, the lingering object that causes the error message to be removed is located in the corp.company.local domain. However, the <GUID=ae856ce5-839a-4e44-b2fb-f37082ca2555> from the objects-list.txt file is associated with a domain controller in the company.local domain that does not have a writeable partition for corp.company.local.
Obtain the GUID of a server in the corp.company.local domain by running the following command:
ldap_search_s(ld, "DC=company,DC=local", 2, "(cn=User*)", attrList, 0, &msg) Result <0>: (null) Matched DNs: Getting 4 entries: >> Dn: CN=User\, Joe,OU=Exec,OU=Corporate Users,DC=corp,DC=company,DC=local 1> canonicalName: corp.company.local/Corporate Users/Exec/User, Joe; 1> cn: User, Joe; 1> description: CEO; 1> displayName: User, Joe; 1> distinguishedName: CN=User\, Joe,OU=Exec,OU=Corporate Users,DC=corp,DC=company,DC=local; 4> objectClass: top; person; organizationalPerson; user; 1> objectGUID: 814226ed-3414-4193-b96d-3a5ea4bf9351; 1> name: User, Joe; >> Dn: CN=User\, Joe,OU=Migration,DC=corp,DC=company,DC=local 1> canonicalName: corp.company.local/Migration/User, Joe; 1> cn: User, Joe; 1> description: Disabled Account; 1> displayName: User, Joe; 1> distinguishedName: CN=User\, Joe,OU=Migration,DC=corp,DC=company,DC=local; 4> objectClass: top; person; organizationalPerson; user; 1> objectGUID: 514f7510-451a-4297-8129-9b4c8ab79axx; 1> name: User, Joe;
repadmin /showreps DC-nameIn this command, DC-name is a placeholder for the name of a domain controller in the corp.company.local domain. Change the GUID in the Objects-list.txt file to match the GUID of the domain controller in the corp.company.local domain. In this example, the Objects-list.txt file will appear as:
The first GUID is the GUID of the domain controller in the corp.company.local domain. The second GUID is the GUID of the lingering object from the Lightweight Directory Access Protocol (LDAP) search.
<GUID=c4fd9c30-b433-40a1-a862-9fdf1f804dc8> : <GUID=514f7510-451a-4297-8129-9b4c8ab79a7c>
When you run Walk-servers.cmd, the command will now complete successfully without the -2147016672 error.
