removal of one of my AD-Integrated DNS servers

I have a domain with multiple AD-Integrated DNS servers. I want to
rebuild one of them.

Do I just use dcpromo to demote the one DC then use add/remove
programs to delete DNS from the server?

Any help would be appreciated.

You could simply uninstall DNS and reinstall it. No need to demote and repromote.

What exactly is going on? Maybe the problem is elsewhere? Would you like assistance?

Hello flyersix,

If you just will uninstall DNS then there is no need to demote it. Just choose
add/remove windows components.

I am not sure if this is the correct spot for this post. My original
problem is two out of my three 2003 DCs where upgraded from 2000 and
as a result the system root directory is WINNT instead of WINDOWS. I
am concerned about complications in performing an full system restore
from Backup Exec tapes if the need arises.

My thought was to wipe the upgraded DCs clean and install 2003
directly to eliminate the possible problems with restoring. I thought
if I performed the procedure on one first then when it was fully up
and running work on the other...since they are both on the same subnet
for redundancy.

Both upgraded systems are running Active Directory Integrated DNS as
well.

I wouldn't see a problem with restores as long as the backup was created
recently from the existing installation, meaning it will know it is WINNT
and not Windows. So I think that is a moot point. As for upgrading, I
usually shy away from upgrades because of the *junk* left behind from the
previous operating system and would rather opt for a fresh installation. If
the DCs are just DCs, meaning they have nothing else installed on them. I
would just demote them out of the domain, wipe out the OS, and install
fresh, and promote it back in when done.

Other than that, are you seeing any errors or any issues going on with the
current installations?

The servers also have DNS running on them. That is why I am wondering
about the proper procedure for both demoting the DCs and removing DNS
from them. They also each have a application running on them but
they are self contained in one folder which is easily moved then
restored.

My hope would be to transfer the FSMO roles from one to the other,
then demote the one, then remove DNS to hopefully not leave anything
messed up in DNS or Active Directory. Once cleanly out of AD and DNS
I would wipe the O/S and reload fresh directly to 2003 then promote
and then install DNS lastly reinstall the application.

Does this make sense/ am I missing anything that could cause problems?

Thanks Again for any input

Hello flyersix,

You can follow this one to remove AD/DNS form the server:
http://technet.microsoft.com/en-us/library/cc755937.aspx

After that check that DNS is complete cleaned from it. Then you can start
with a fresh install and promote it again to DC. As long as you have no errors
on the DC's you can do it, if any kind of errors exist solve then first and
the demote the server.

To check the DC's run replmon from the run line or repadmin /showrepl (only
if more then one DC exist), dcdiag /v and netdiag /v from the command prompt
to check for errors, if you have some post the complete output from the command
here or solve them first. For this tools you have to install the support\tools\suptools.msi
from the 2000 or 2003 installation disk.
