Best way to replace a server and do clean install

We will be replacing our old Win2K3 Server with a new one shortly. Not only
is the actual hardware antiquated, but the OS has been experiencing many
problems over the last year and I look forward to a clean install.

Since I am doing a clean install instead of some type of migration all of
the users will have to be manually re-added to the domain. There are only 14
users so this is not a terrible task.

My concern is that when I try to add the old user to the new domain it will
create a new user account for them on their local machines and that all of
their personal settings and desktop etc will be "lost".

Am I making this into a bigger project then it really is?
Will I just be able to go to each machine, log on with admin account and
join the "new" domain and the same user account on the Workstation side will
be used?

Any other advice?

Thanks.
 
Re: Best way to replace a server and do clean install

Hello Jack,

!!!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?

Add the new server after fresh install as additional DC, install DNS DHCP
and give it time for replication. Then make it Global catalog server and
move the 5 FSMO roles. After that copy your data, if needed. So the only
change for the users will be a new data server if this one is used for and
a new DNS server which will be provided with the DHCP scope options.

See here for step by step:
- 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 (Directrory 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

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


Demoting from the first DC:

- 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

Re: Best way to replace a server and do clean install

Hello Jack,

It isn't comlicated, just some more steps that you might saw before. But
everything is really easy to do. You will see.

Re: Best way to replace a server and do clean install

It's actually a lot less complicated than rebuilding the domain. Do a
search on the MS Knowledge base (and Google) and you'll find some very
good step by step processes for this.

If the DC in question is the only one, I would suggest you:

1) build the new DC and migrate to it as Meinolf described.
2) Take the old DC off line for several days
3) If everything works, power up the old DC.
4) Use DCPROMO to make the old DC a member server
5) Remove it from the domain. Clean up AD to remove any leftover entries
(DNS also)
6) Rebuild the server (clean install) and DCPROMO it as a second DC.

It's vital that you have more than one DC in a domain. Think about what
would happen if you were to lose the only DC.... Having a second DC
makes it possible to keep operating until the failed DC can be rebuilt
and/or replaced....

BTW, the process that Meinolf described assumes that the OS on the new
server is the same as on the old one. If you were to go with, say 2008,
you would have to upgrade AD first....
