The semantic database analysis checker that is included with Ntdsutil.exe may not be able to fix a mangled subref (830379)


The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server

SYMPTOMS

The semantic database analysis checker that is included with the Ntdsutil.exe tool may not be able to fix a mangled subref. In this scenario, Active Directory replication may fail, and event messages that are similar to the following may be logged in the Directory Service event log:
Event Type: Warning
Event Source: NTDS KCC
Event Category: Knowledge Consistency Checker
Event ID: 1265
Date: Date
Time: Time
User: N/A
Computer: Computer_Name
Description:
The attempt to establish a replication link with parameters

Partition: DC=vgo,DC=ae,DC=aena,DC=es
Source DSA DN: CN=NTDS
Settings,CN=EAS0101,CN=Servers,CN= name,CN=Sites,CN=Configuration,DC= name,DC=es Source DSA Address: 339ca0d9-7dd7-4e15-bbee-1998387e4634._msdcs. name.es Inter-site Transport (if any): CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC= name,DC=es
Event Type: Error
Event Source: NTDS Replication
Event Category: Replication
Event ID: 1645
Date: Date
Time: Time
User: Everyone
Computer: Computer_Name
Description:
The Directory Service received a failure while trying to perform an authenticated RPC call to another Domain Controller. The failure is that the desired Service Principal Name (SPN) is not registered on the target server. The server being contacted is 339ca0d9-7dd7-4e15-bbee-1998387e4634._msdcs. name.es. The SPN being used is E3514235-4B06-11D1-AB04-00C04FC2DCD2/339ca0d9-7dd7-4e15-bbee-1998387e4634/eas CNF:3311d1ff-608f-411c-97dc-56d221e04bab.ae.aena.es@eas CNF:3311d1ff-608f-411c-97dc-56d221e04bab.ae. name.es.

Please verify that the names of the target server and domain are correct. Please also verify that the SPN is registered on the computer account object for the target server on the KDC servicing the request. If the target server has been recently promoted, it will be necessary for knowledge of this computer's identity to replicate to the KDC before this computer can be authenticated.
When you try resolve this problem by using the semantic database analysis checker that is included with Ntdsutil, you cannot resolve the problem, and you may receive a message that is similar to the following: ntdsutil: sem d a semantic checker: go fix Fixup mode is turned on
Opening DIT database... Done.

The object must be removed or renamed before the mangled name may be corrected.

Can't fix Mangled NC Error.

RESOLUTION

To resolve this problem, install this hotfix on the domain controller that has the name-mangled object, restart the computer in Dsrepair mode, and then run the Ntdsutil go fix command to use the semantic database analysis checker on the Ntds.dit database. In Dsrepair mode, clients may receive an "Access denied" error message if they try to access DFS Root or DFS Link information on the computer. The generation of the error message is by design. This hotfix includes a new version of Ntdsutil.

Note To start the domain controller in Dsrepair mode, press F8 during the startup process, and then select Directory Service Restore Mode in the Advanced Options menu.
