The Windows Server 2003 Active Directory Domain Rename Tools 'Read Me First' contains:
The Windows Server 2003 Active Directory Domain Rename Tools provide a security-enhanced and supported methodology to rename one or more domains (as well as application directory partitions) in a deployed Active Directory forest. The DNS name and the NetBIOS name of a domain can be changed using the domain rename procedure. For an understanding of the constraints of the domain rename procedure, please see the accompanying document, "Understanding How Domain Rename Works," available on this page.
Note: These tools are for use with Windows Server 2003 only. Do not use them with Windows 2000.
Important: The domain rename operation and the use of the domain rename tools is not supported in an Active Directory forest that has any version of Microsoft Exchange Server prior to Exchange Server 2003 SP1 deployed in it.
