Can anyone point me to a step by step for upgrading my 2 dc's from 2000
to 2003? I have a new server to replace one of them with. They both
are also dns servers with other network services.

Hello Phil,
!!!NEVER START BEFORE HAVING CREATED A BACKUP OF YOU DATA/MACHINE!!!
One question first:
Is the old server also Exchange server and will it be taken out of the domain
forever, when the new server is running?
- On the old server open DNS management console and check that you are running
Active directory integrated zone (easier for replication, if you have more
then one DNS server)
- run replmon, dcdiag and netdiag on the old machine to check for errors,
if you have some post the complete output from the command here or solve
them first
- run adprep /forestprep and adprep /domainprep from the 2003 installation
disk against the 2000 server, with an account that is member of the Schema
admins, to upgrade the schema to the new version
- Install the new machine as a member server in your existing domain
- configure a fixed ip and set the preferred DNS server to the old DNS server
only
- run dcpromo and follow the wizard to add the 2003 server to an existing
domain
- if you are prompted for DNS configuration choose Yes (also possible that
no DNS preparation occur), then install DNS after the reboot
- for DNS give the server time for replication, at least 15 minutes. Because
you use Active directory integrated zones it will automatically replicate
the zones to the new server. Open DNS management console to check that they
appear
- if the new machine is domain controller and DNS server run again replmon,
dcdiag and netdiag on both domain controllers
- if you have no errors, make the new server Global catalog server, open
Active directory Sites and Services and then double-click sitename, double-click
Servers, click your domain controller, right-click NTDS Settings, and then
click Properties, on the General tab, click to select the Global catalog
check box (http://support.microsoft.com/?id=313994)
- Transfer, NOT seize the 5 FSMO roles to the new Domain controller (http://support.microsoft.com/kb/324801)
- you can see in the event viewer (Directory service) that the roles are
transferred, also give it some time
- reconfigure the DNS configuration on your NIC of the 2003 server, preferred
DNS itself, secondary the old one
- if you use DHCP do not forget to reconfigure the scope settings to point
to the new installed DNS server
- reconfigure your clients/servers that they not longer point to the old
DC/DNS server on the NIC
- to be sure that everything runs fine, disconnect the old DC from the network
and check with clients and servers the connectivity, logon and also with
one client a restart to see that everything is ok
- then run dcpromo to demote the old DC, if it works fine the machine will
move from the DC's OU to the computers container, where you can delete it
by hand. Can be that you got an error during demoting at the beginning, then
uncheck the Global catalog on that DC and try again
- check the DNS management console, that all entries from the machine are
disappeared or delete them by hand if the machine is off the network for ever

The easiest way to do this is to perform an "upgrade in place" on the DC
you intend to keep(boot it into Windows 2000, put in the 2003 CD and
choose the upgrade option) making sure it:
1) holds all of the FSMO roles
2) is a global catalog server
3) Holds all of your DNS ADI or standard primary zones (not secondaries)
This will be your ONLY DC after you finish the next step, so it must be
capable of handling ALL DC functions.
When the upgraded DC comes up and everything checks out as working, do a
clean install on your new server, join it to the domain, and promote it
to a DC. Transfer FSMO roles to it as you see fit. Demote the one you
intend to retire and gracefully unjoin it from the domain. You can stop
here if you want.
If you want all clean installs, after transferring ALL the FSMO roles to
the new server, insuring that it is a GC, DNS is working, AD has fully
replicated, etc., demote the old one and unjoin it. Do a re-partition,
reformat and a clean install.
This is probably a good idea, especially if your W2K system partition
was small. W2K3 needs more room. The 10G recommended is way too small
IMHO. 30G is a better number, especially if it is a terminal/app server.
If your DCs perform other tasks (file server, web server, etc.) you'll
need to duplicate those shares, websites, etc. If any are exchange
servers, be sure to research that - it adds a fair bit of complication.
As always, backup everything before you start this, have a clear and
well thought out plan. Know exactly what you are doing, in what order
and exactly what you are going to do if any part of it fails. Always
leave yourself a way to recover. That said, this is a tried and true
method that I've done many times and it generally goes off without a hitch.
