DCPROMO then change IP? [message #157265] Fri, 03 July 2009 13:21 Go to next message

In the past I've always ran the DCPROMO on site to pull down active
directory, then fully configure.

Has anyone DCPROMO in local site, then changed the IP settings to a remote
subnet?

I know I'll need to move server in sites and services. But has anyone
encountered replication or DNS problems doing this task?

The issue is that I have a remote site with a faulty domain controller and
it will be more cost effective and less time consuming to configure new
machine locally, change IP settings to remote site, then ship for a user to
connect, before completing final tests remotely.

Any comments are appreciated.

You should be able to do this - although you will need to move manually the
domain controller to the appropriate site (also make sure to verify that its
SRV records are registered in appropriate, site-specific parts of the DNS
namespace.
If you want to avoid this, you can create a local subnet, assign it to the
remote site, and install/promo the DC while connected to it. Afterwards, you
would simply need to change its IP address and modify the corresponding DNS
A/PTR records...
On a related subject, make sure that the carrier you choose has proper
security measures in place...

Hey hozzie,
I'd just like to confirm with Marcin that this is indeed no problem at all.
As Marcin said, the main concern with doing this is DNS. Just make sure all
of your records are changed to reflect this change. A records for the
domain, the domain controller, SRV records, records as nameserver and so on.

I've done this numerous times no problem.

Hope you got what you need. :)

Duncan

Hello hozzie,

You can change the ip address from a DC without any problem when you control
that changes are correct in all DNS zones and the subfolders. Do not forget
to change, if used, some application servers that maybe use an ip address
instead of a server name.

Also you have to adjust AD sites and services and maybe the clients need
the new ip address if the server is also DNS server. Just change the ip,
run ipconfig /flushdns and ipconfig /registerdns and restart the netlogon
service. Then check replication.

Best regards

It's important to verify if the domain controller is a DNS server as well
with active directory integrated zone, modify the server options of the scope
or scopes of the DHCP, because probably scopes were using the old DNS IP.
Finally, as somebody told before you have to be careful with the LDAP
applications which are working with the old IP instead of the FQDN of the
domain.
