I would like to know what are the things I should look out for if I change
the IP address of a domain controller?What is going to break and how do I
fix them. I am moving the domain to a new location so it needed a new IP
scheme with 3 other DCs in different locations. Thank you in advance.

Hello Jonathan,

No problem with changing ip address, before starting make a backup of course,
then run support tools dcdiag /v, netdiag /v and repadmin /showrepl to check
for errors in the domain. If no errors exist change the ip address and run
ipconfig /flushdns and ipconfig /registerdns. Then restart the netlogon service
or reboot the server. Make SURE you use the DC which is also DNS server or
you have already configured a reachable DNS server.

Best regards

Meinolf Weber

If any workstations or servers reference the old IP address as one of
their DNS servers, you will need to change them to point to the new IP
address (or a different one).

If you are using dhcp and the dc has a fixed address, make sure to change
the reservation. If your clients recieve their dns address within dhcp make
sure to change the options to reflect this change. When you bring up the
dc, modify the static address and verify any machines that refer to the
dc/dns server that they use a host name and not an ip address. One thing
that pops to mind is a secondary dns server (If you have one) or a WINS
server. Verify they all are pointing properly if using static addresses.
If you have a dmz and there are clients that need to come back inside,
verify that the ports are properly configured for the new location, this is
quite a common error when moving a dc.
