Perform Attribute Cleanup

Updated: October 15, 2008

Applies To: Windows Server 2008, Windows Server 2008 R2

You can use this procedure to perform attribute cleanup after a domain rename operation. This post-domain-rename cleanup procedure removes all values of the msDS-DnsRootAlias and msDS-UpdateScript attributes from Active Directory Domain Services (AD DS) that were written during the domain rename operation.

ImportantImportant
Perform this cleanup procedure only after all member computers in the renamed domains have been restarted as described in Restart Member Computers. If smart card logon is used in your environment, make sure that all authentication certificates have been renewed before this step; otherwise, authentication will start to fail for the certificates.

Membership in the Enterprise Admins group in the target forest (with write access to the Partitions container object and the cross-reference objects that are its children in the configuration directory partition) and the Local Administrators group (or write access to the domain rename C:\domren working directory) on the control station computer is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

noteNote
You can use credentials other than the credentials with which you are currently logged on. To use alternative credentials, use the /user and /pwd command-line switches of rendom, as described in Appendix A: Command-Line Syntax for the Rendom Tool.

  1. On the control station, click Start, click Run, type cmd, and then click OK.

  2. At the command prompt, type the following command to change to the working directory, and then press ENTER:

    C:\domren
    
  3. From within the working directory, type the following command, and then press ENTER:

    rendom /clean
    

    The rendom /clean command removes the values for the msDS-DnsRootAlias and msDS-UpdateScript attributes from AD DS by connecting to the domain controller that has the domain naming operations master role.

After the steps in this procedure are complete, the new forest is ready for another domain rename (or forest restructuring) operation, if necessary.
