Removing 1 of my AD intergrated DNS servers..

[Autram Jacobs]

What is the best way for me to remove 1 of my AD
intergrated DNS servers?

I am moving the Windows 2000 system and apps of one of my
servers to new hardware...and this box I want to migrate
just happens to be an AD intergrated DNS server as well
as a DC.

So to simplify the move I plan to remove AD by using
DCpromo and also remove the DNS services so that at the
end of the day I only need to move data and apps during
my migration..which minimizes possible problems with AD
and DNS after the move if I have taken that out of the
equation.

I can't seem to find any docs on the knowledgebase.

Just make sure no other machines are using this server for DNS in their IP
properties. Double check the same that you've removed it from your DHCP
scope options. Then remove the DNS service. Then demote with dcpromo.

Do you plan on installing another DC with DNS? Recommended to have a min two
DCs per domain.

First, uninstall DNS. Point the DNS settings in TCP/IP to the remaining DNS server and DCpromo the box down. Then make sure that none of the other
machines are pointing to this DNS server for DNS. You will then need to clean up the old DCs entries in the remaining DNS server. Anything that refers to the
old servers name or IP in the _msdcs, _sites, _tcp, _udp keys will need to be removed. For about an hour after cleaning up DNS, clients could potentially
experience problems logging in though. Once the client's expire their DNS cache, then things should return to normal. Some clients may also need to reset
their secure channels. A reboot should take care of that.
