I can confirm this bug on kubuntu 6.06. Adding a DNS server using the GUI (K->System Settings->Network Settings->Administrator Mode-> Domain Name System-> Add...) is not persistent across reboots.
Manually adding "dns-nameservers xxx.xxx.xxx.xxx" in /etc/network/interfaces resolves the issue. I guess that new users are not expected to figure this out. -- network-admin needs dns-nameservers line in /etc/network/interfaces for static IPs https://launchpad.net/bugs/25624 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
