Hi all, Im a bit new to linux I've setup samba 4.0.4 as a PDC using the samba internal dns on ubuntu 12.10 and all is working well. with exception of one issue On reboot I cant ping hostnames local to my dns on the PDC but I can reslolve them with the internal dns fine. I can also ping external hostnames from the PDC though. on the PDC it will just take a while to display host not found after pinging a hostname resolved by the DNS (I can ping whatever is in /etc/hosts fine) On the clients pointing to the DNS server they are able to ping the hostnames fine. The catcher is I can ping all internal dns hostnames after service networking restart on the Samba PDC. What could be stopping it from allowing it to ping hostnames it can resolve? Also for it to work I have to restart the whole service, not just a ifdown ifup Thanks
