Update DNS records on server after IP change

Posted on 2012-08-23

Hi all,

I have built a server offsite using a different set of IP details than the ones implimented on the network the server is destined for.

After I put the server on the new network and changed its IP address I noticed DNS has all the old IP address listed in its "A" records etc and I wondered if there was an easy way to re-set the forward and reverse lookup zones to use the new IP address.

I was going to just recreate the zones but thought there must be a more simple way.

I also have an issue where the client PC's can't find the server when I try to join them to the domain. I am assuming the reason for this is the incorrect IP listings in DNS for the server.

As always any help greatly appreciated.

    you can use ipconfig /registerdns from the command line to re register in DNS,
    but you will have to clean up the zones as the above command does not update the zone properties - soa records etc.
    It will also not remove the old dns host entries in forward and reverse lookup zones, so the hostname will resolve to different ips each time you query it.

    Hi Leslie,

    Ipconfig /registerdns don't work gives me an error "The requested operation requires elevation" ?

    Any idea what that means

    you need to start the command prompt as Administrator.  Click on Start, then right click on command prompt and select Run as Administrator from the pop up menu.
