Change DNS settings on NICs automatically

Posted on 2011-04-22
Last Modified: 2012-05-11
I just migrated to new 2008 DCs and transferred dhcp settings from the old to new dc's and added the new dc's ip's in the dhcp scope settings accordingly. I still havent decommissioned the old 2003 dcs yet. What I want to do now is change the static dns ip settings on allthe servers to the new dc's. Is there a way to do this automatically somehow instead of manually going into every server and chaanging the ips?

    The best solution would be to go to each server and change the static IP address since you know that you have changed then verified that changes took place.

    You could write a small script doing this (look here for an example, although, to be honest, I think better way would be to create reservations for the servers in the DHCP and assign IPs and DNS' from there, unless you want to get into this in the future. AFAIK there's no built-in way for you to change DNS settings on multiple servers (besides the script, of course).

    I usually give the ip addresses of the old servers to the new servers so that I don't have to reconfigure any statically assigned devices.
