i have multiple sites on the same box. they use the same nameservers to resolve. suddenly after restarting the box, some sites resolve and others don't how can i figure out what's causing this?

  Hello :) How long ago did you reboot the system? Do the domain names resolve locally? EX: dig @localhost domain.com
  Thank you.

  rebooted them less than an hour or two ago and this happened. this is the output i get from that command: ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.6 <<>> @localhost domain.com ; (1 server found) ;; global options: printcmd ;; connection timed out; no servers could be reached (just to clarify, i did of course swap domain.com with my own domain, just switched it back for privacy reasons)

  Please check to make sure no firewall rules are blocking connections. Also, try rebuilding the DNS configuration via: mv /etc/named.conf /etc/named.conf.backup /scripts/rebuilddnsconfig
  Thank you.

  the output of that is as follows: root@snowwhite [/scripts]# /scripts/rebuilddnsconfig Including rndc key file to named.conf Adding controls clause How exactly do I go about checking the firewall? No rules should've been changed recently anyway

  Sometimes rules are restored after a reboot if they were not saved correctly. Do you use a third-party firewall such as CSF? If not, you can temporarily disable iptables via: /etc/init.d/iptables stop
  Thank you.
