Hi,

I am trying to remove the static DNS servers on one of our Windows 2019 server by selecting “Obtain DNS server address automatically”. But when I restart the server, it reversed back to the static DNS server as setting previously.

Please advice how can I resolve this issue.

    Hi,

    Thanks for posting in Q&A platform.

    Based on provided information, my understanding is you would like to set the Windows server 2019 automatically get DNS from DHCP. After checking the following option and then rebooting the device, the DNS server reverted back to static addresses. Is that right?

    May I know if the server 2019 can obtain IP address from DHCP server successfully or connect DHCP server successfully?

    If yes, I would suggest to check whether the DNS server was set correctly in Scope Options on DHCP server.

    I would also suggest to check if group policy, task scheduler may case this issue.

    Best Regards,
    Sunny
