Thanks Nick for helping

I'm not using AD connector. In the past night the file /etc/resolv.conf has changed back to original and my DHCP page isn't loading anymore. There is also a file called /etc/resolv-peerdns.conf it has this content witch are the 3 DNS server IP's I entered at the /Network/Settings/IP Settings page.




My system by the way has Multiple WAN with 1 static configured WAN interface and 1 dynamic configured WAN.

The file /etc/resolv.conf is generated by /usr/sbin/dhclient-script so I think this script is somehow collecting wrong data.
