Hello Blue,
The domain rename operation is supported within an Active Directory
forest if, and only if, all domain controllers in the forest are
running Windows Server 2003 Standard Edition, Windows Server 2003
Enterprise Edition, or Windows Server 2003 Datacenter Edition, and
the forest functionality has been raised to Windows Server 2003 or higher.
Therefore, before you
can rename a domain in your Active Directory forest, you must ensure
that the forest functionality has been raised to at least Windows
Server 2003.
So to use it you must upgrade the 2000 DC's and change to Windows
Server 2003 mode.
If you have additional hardware in space you can also try ADMT v3:
