Migrating 2000 server

[hmcmahan]

I am wanting to upgrade a 5 year old DC to a new server. I am basically
wanting to move active directory to a new server and make the old server a
backup DC.
I have downloaded the ADMTv2 program and reading thru it. But I guess never
have done this before, I am wanting to know is there an easier way to migrate
a Windoew 2000 server to another Windows 2000 server?

I am wanting to upgrade a 5 year old DC to a new server. I am basically

wanting to move active directory to a new server and make the old server a
backup DC.

There is no such thing as a backup DC in Win2k.

I have downloaded the ADMTv2 program and reading thru it. But I guess
never
have done this before, I am wanting to know is there an easier way to
migrate
a Windoew 2000 server to another Windows 2000 server?

It does not sound like you want to replace your current server with a new
server. It sounds like you just want to add another server to the domain. If
so just add the new server to the domain as a member server (join it to the
domain the same way you would an XP or 2000 computer) then run dcpromo on
the new server to make it a DC and the AD info will replicate to the new
server and your done. Don't use ADMTv2.

Hello hmcmahan,

- 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

- 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 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, better for
redundancy to have more then one DNS server

- 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), also better for redundancy
to have more then one Global Catalog server

- Transfer, NOT seize the 5 FSMO roles to the new Domain controller (http://support.microsoft.com/kb/255690)

- you can see in the event viewer (Directrory service) that the roles are
transferred, also give it some time

- reconfigure the DNS configuration on your NIC of the new 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

- export and import of DHCP database (if needed) http://support.microsoft.com/kb/325473


Demoting the old one , if needed for the future:

- 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
