It doesn't work (for Win2000). You cannot even EASILY rename
domains in Win2003 except in one very special case.

You can re-install a new server with same name (after this one is gone),
or you can rename a NON-DC and promote it (after this one is gone).

If you hard drive has not yet failed (completely) you could also do a
System State backup of this running DC, or other methods of moving the
contents of the failing drive to new disk.

Only after this DC (the machine) is removed from the network.

You cannot have two machines on the same net with the same
NetBIOS name and expect them to function -- nor two DCs with
same name.

No, it's both worse AND better than that -- if you don't don it correctly
the new DC won't even promote or work; if you do it correctly you will
not have any SID problems.

Unless you have this DC doing "other things" there is no particular
reason for it to even have the same name.
