Domain names are a critical part of the proper functioning of a Group Policy implementation. In the Windows Server 2003 family, administrators can rename a domain. This is accomplished by using the Rename Domain Tools available for download from the Windows Server 2003 Domain Rename Tools link on the Web Resources page at https://www.microsoft.com/windows/reskits/webresources. The Domain Rename tools provide a secure and supported methodology to rename one or more domains (as well as application directory partitions) in a deployed Active Directory forest.

  • Be sure to back up all your GPOs using GPMC after domain rename is complete. Backups made prior to domain rename cannot be used for Restore after a domain rename.

Renaming one or more domains is a complex process that requires thorough planning and understanding of the domain rename procedures. You must also modify any affected GPOs so that they work correctly. To modify the GPOs, use the Gpfixup.exe tool, which is included with the Domain Rename tools. Gpfixup.exe repairs GPOs as well as GPO references in each renamed domain. It is necessary to repair the GPOs and the Group Policy links after a domain rename operation in order to update the old domain name embedded in these GPOs and their links.
