Error Deleting a Domain Controller Account in Active Directory Users and Computers

Article ID: 247393

Article Last Modified on 3/2/2007



APPLIES TO

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Datacenter Server



This article was previously published under Q247393

SYMPTOMS

When an administrator uses Active Directory Users and Computers Management Console to remove a computer object, the administrator may receive the following error message:

The object YOURCOMPUTER (or some of the objects it contains) cannot be deleted because Critical Directory Service System objects cannot be deleted during tree delete operations. The tree delete may have been partially performed.

Microsoft recommends that you remove a Windows 2000 Domain Controller from a domain by using the DCPromo.exe tool to demote it. An administrator might need to remove an account for a Domain Controller that is no longer present.

CAUSE

This error message can occur if the connection objects for the server are still present for the domain controller.

RESOLUTION

To resolve this issue, delete the Domain Controller's server object from Active Directory Sites and Services Management Console. This also deletes any connection objects.

If you continue to experience this issue, you need to remove the connection object for the Domain Controller by using NTDSUTIL. For additional information about using NTDSUTIL to remove the connection object, click the article number below to view the article in the Microsoft Knowledge Base:
