IP Change on DC


G

Guest

Hi
I have to change the static IP on a domain controller to a different subnet. I know that I will have to change the site subnet in AD sites and services. Once this is changed, along with the D/G is there any other gotcha's that I might run into? The host name is not going to change either

The DC is a W2K server/SP4. It is a Global catalog and replication is fine.

It might be an idea to update the all the DNS' in the domain to make sure
the replication recovers in minimum time. Apart from that, it sounds
perfect.
Oops, if you are using DHCP, change those settings as well. Make sure the
machines in the domain or old subnet have new IP addresses for another DNS
server or are already using the new address.

Active Directory lives and dies on DNS, so make sure that your DNS records
update correctly when you make the change. Depending on the size of your
environment and how your other machines are caching their DNS records, you
might run into some spottiness immediately after the change. But for the
most part, it's nothing that an 'ipconfig /flushdns' shouldn't be able to
fix.
