When checking your messages file on a Linux server
tail -f /var/log/messages
you might see something like:
network 0.0.0.0/0: no free leases
This means dhcpd is not running correctly. You can fix dhcpd if you think you need it. Since it's not working correctly, in most cases you can just disable it. You will need to have a static IP running on the server to have remote access.
systemctl stop dhcpd.service
You can always start it back up again anytime
systemctl start dhcpd.service
By default dhcpd does not activate on boot, so disabling it will fix the no free leases error until you manually start dhcpd again.
