  • DNS Suffix Snafu

    Went through the rendom process almost two months ago and from all appearances, all went well as there were no errors generated at each step. I just discovered this morning that the original domain suffix is still being attached to the client network adapter. ipconfig /all shows the primary dns suffix as being the new domain name but the suffix search list shows first the new primary dns suffix followed by the old dns suffix. The connection specific suffix however shows the old dns suffix. Our domain controller servers as both the DNS & DHCP server along with a backup domain controller. How do you go about eliminating the old dns suffix?

    Remove it from the NIC. There's no need to have it there.

      i worked at modifying the nic settings but could not find anywhere to remove the reference. the domain controller is set to dole out static ip addresses to specific client computers and the settings for the nic are such that they obtain dns and ip address settings automatically. is there another method to use? command line maybe?

        Check your DHCP scope settings

          If I understand your issue correctly, then this could be done via GPO

            i did check the dhcp scope and there wasn't anything that was out of place. i did review the posted link and yes, i found two entries in the tcpip parameters that had the old domain listed and made changes but even though the changes were made, upon reboot the settings of the old domain were written back. i didn't do the gpo fix as we don't have that many clients in the network.

              I was able to correct this issue finally. Since every time I made modifications to my registry and the old domain name came back I thought it was a group policy setting but it wasn't. Turns out it was in the DHCP scope and I found it in the Server Options....DNS Domain Name setting. Changed that and all is as it should be now. Thanks for the help
