DNS during Domain Controller demotion

Windows Server 2003.  Does DNS get removed by the dcpromo wizard when
demoting a domain contoller.  This is just one of many domain controllers in
a domain.

Hello ShrikeAttack,

Do you use AD integrated zones? Then you will use DNS service for this server.
Reconfigure it to use another available DNS on the NIC. If it is a secondary
DNS server the role has to be uninstalled via add/remove programs.

Best regards

Hi
The DNS service is not removed. But DNSAI only works between DCs that are
also DNS servers. Assuming that your existing DCs are also DNS servers, make
sure that the network clients are configured to use them. If you plan to use
that DC (to be demoted) as DNS server (although you removed the DC role),
you can replicate DNS settings using a secondary zone on that server.

I hope that the information above helps you.

The DNS is integrated in AD and I have another DC setup with DNS.  My DHCP
server is also looking at the new DNS server.

According to this link DNS should be installed and properly functioning
prior to demoting the server. 
http://technet.microsoft.com/en-us/library/cc755937.aspx
Can I safely assume I can uninstall DNS using add/remove software after the
server has been demoted?  Is there anything I should consider so I get a
clean break from the other DNS servers in my environment?

Thanks

Hello DNS,

Make sure all machines use the new DNS and check after removing the DNS role
that also in the DNS zones the server is removed as DNS server.

The requirement that it is up and running is based on if the DC is pointing
to itself for DNS. You can always point it to one of the other DCs' DNS
server and remove it's own IP from IP properties so it is not reliant on
itself. This is how I normally remove a DC iIn such a scenario with other
available DC/DNS servers. If you do it this way, and now knowing that the
current installed DNS server is not being used, do NOT delete any AD
Integrated zones while it is still a DC, otherwise you will remove the zone
from the whole infrastructure. Unistall it from Add/Remove.

As long as the clients have a DNS available to use, you should be fine. IF
your existing DC is also a DNS server, just point the clients to that DC.
