adprep.exe /domainprep /gpprep
When you do this, you receive the following error:
Domain-wide information has already been updated.
[Status/Consequence]
Adprep did not attempt to rerun this operation.

Adprep is about to upgrade the Group Policy Object (GPO) information on the Infrastructure Master FSMO dc1.corp.contoso.com.

Gpprep operation 3 failed.
[Status/Consequence]
Upgrade of domain Group Policy Objects failed.
[User Action]
Check the log file ADPrep.log and gpprep.log in the C:\Windows\debug\adprep\logs\20120809082547 directory for possible cause of failure.

Adprep encountered a Win32 error.

Cause

The infrastructure operations master role holder in this domain implements a disjoint namespace. Adprep.exe assumes that computer names will match their domain names because this match is the default behavior in all versions of Windows.

Resolution

Note All steps require membership in the Domain Admins group. Also, run commands at an elevated command prompt.
  1. Locate the infrastructure master role holder in the domain. To do this, run the following command:
    netdom.exe query fsmo
  2. Disable incoming and outgoing (also known as " inbound and outbound") replication on the infrastructure master server. To do this, run the following command:

    repadmin.exe /options <infrastructure_master_name> +DISABLE_OUTBOUND_REPL +DISABLE_INBOUND_REPL
  3. Log on to the infrastructure master server, and modify its Domain Name System (DNS) suffix. To do this, follow these steps:
    1. Start SYSDM.CPL, click OK, click Change, and then click More
    2. Set the suffix in the Primary DNS suffix of this computer box to match the Active Directory Domain Services (AD DS) domain name instead of the current disjointed name.
  4. Restart and log on to the infrastructure master server, and then run the following command:
    adprep.exe /domainprep /gpprep
  5. Use SYSDM.CPL, and then follow the steps in step 3, except this time in step 3B, you must set the suffix in the Primary DNS suffix of this computer box to match the original disjoint name on the infrastructure master server.
  6. Restart and then log on to the infrastructure master server, and enable inbound and outbound replication. To do this, use the following command:
    repadmin.exe /options <infrastructure_master_name> -DISABLE_OUTBOUND_REPL -DISABLE_INBOUND_REPL

More information

Gpprep adds cross-domain planning functionality for Group Policy and Resultant Set of Policy (RSOP) Planning Mode. Adding this functionality requires updating the file system in SYSVOL and AD DS permissions for existing group policies. The environment may already contain custom or delegated permissions that were manually implemented by administrators. In this case, gpprep triggers replication of all Group Policy files in SYSVOL and may deny RSOP functionality to delegated users until their permissions are recreated by administrators. Therefore, Administrators should run gpprep only one time in the history of a domain. Gpprep should not be run with every upgrade.


Notes
  • Gpprep was introduced in Windows Server 2003.
  • Disjoint namespaces are not a Microsoft best practice.
