We have 4 DCs, each one at a different site. The main DC, with the global
catalog running windows 2000 in mixed mode resides in NY. The 4 DCs are on
machines that are 10 years old and need to be replaced. Ideally, I would like
to replace each site one at a time.I would like to keep the same domain name.
I would also like to transfer the machine name and IP address to the new
server. Below are my 3 options. Which one is best. TIA

1. Use ADMT. From what I read, this tool is only usefull if the domain is
different. Is this true?
2. Replace the DCs with the new 2000 machines, move roles over to the new
machine and perform an
upgrade to Win 2003 using ADPREP/FORRESTPREP AND ADPREP/DOMAINPREP
3. Install a new machine as a windows 2003 member server, promote to DC.

Upgrade -- don't rebuild nor migrate.

Backup and restore onto new hardware -- do repair installs -- keep this
whole part sepepate from the idea of upgrading the domain.

Yes. It is for migrations.

ADPrep (forest and domain) must be run before any Win2000 Forest/Domain
can accept the first Win2003+ DC.

Or upgrade one of the current ones to keep the name -- then migrate ONLY
the OS to new hardware.

"Repair install" or "ASR" is your friend.

Thanks for your response. The current DC machines are 11 years old and out of
warranty. What are the cons of adding a new 2003 machine as a member server
and promoting it?--

Nothing really at all -- but that doesn't directly answer your
interest in keeping the same server names and addresses....

OS's can be physically migrated to new hardware if you want
to meet that (extra) requirement.

Generally the Domain itself however should be UPGRADED.
(That is, add a new Win2003 Server and promote or upgrade
an existing DC to Win2003 as appropriate.)
