Change IP on DC w/DNS and Wins?

Hello everyone,

I have a single DC environment that has a routable IP running AD, DNS, and
WINS We are moving to a new DSL service and will have non-routable IP's.
After the change I will set up DHCP for all the client computers. The DNS is
a local DNS with no forwarding. (domain.local) with 2 external DNS settings.

Questions:
What do I need to know about changing the IP on this server?
What do I need to know about swithching the DNS settings?
What are the risks with AD?

I can uninstall WINS due to a pure WIN2K3 and WinXP environment. It is
mainly DNS and AD on the DC that I am worried about.

Thanks for any advice in advance

Jack

What IPs do you mean by "non-routable"? Do you mean 10.0.0.0 etc. (IP
defined in RFC 1918?). These IPs are very much routable -- they are just
reserverd for "internal" use, but "internal" can even be between me, my ISP
and my customer that uses same ISP.

Do you have one or two network cards in DC?

Changing IPs on DC is not much of a problem. You change IP and DNS setting
on DC. If you are running DNS service on DC server you should point it back
to itself (you can enter 127.0.0.1 under TCP/IP setting for DNS server).
Restart NetLogon service and this should update DNS records. Now you have to
update DNS forwarders so that clients will be able to resolve outside
addresses.

The biggest job is, reconfiguring the clients (well it depends on the number
of clients). You can first setup DHCP with new settings (new DNS settings).
When clients are rebooted they should get new settings.

If you will have a good plan, clients won't even notice any change.

Thanks for the quick reply Miha Pihler

Yes I mean 10.0.0.0 IP RFC 1918.
There is only one NIC in the machine.
If I wanted to keep WINS what proceedure should I follow?

Hi,

You can still use WINS, but I don't think you can gain much from it since as
you have only Windows XP and newer Microsoft operating systems.

In my old environment, as soon as I migrated all servers and clients to
Windows 2000 I removed WINS. You can still migrate it now (change IP) and
disable the service. In case of any problems (there should be none), you can
still enable it.

You are welcome :-)

If you need, you can always post back with your specific "migration" plan
for review and additional help.
