Next, we must unlink the /etc/nf file with the command:įinally, open the nf file with the command: To bypass that issue we’ll stop and disable systemd-resolved with the commands: As is, Samba is working without DNS because your server defaults to systemd-resolved. How to test the DC configurationĪt this point, your Samba Domain Controller is up and running, but there’s a problem. Once that completes, reboot the server again and prepare for testing. This is done with the following commands: To do this, we need to mask, stop and disable the smbd, nmbd, and winbind services and umask, start and enable the samba-ad-dc service.

We’re going to call this server “dc1.” To set the hostname, log in to your Ubuntu Server and issue the command: The first thing we need to do is set the hostname of our machine.
