I would do this in a root terminal

tcpdump port 53

You might need to use /sbin/tcpdump instead.  This will give you a line for 
each packet in or out on port 53, the UDP DNS port.  From this you will 
likely get an idea of what is up.

If you have multiple DNS entries in resolv.conf, it may be that the first one 
is timing out and then it is successfully trying the second one.

What is your iptables situation with incoming UDP port 53?
