[cs615asa] Can't connect to DNS server

[Tejas]

I setup a DNS server on RH6 AMI and seems to work fine when I query on 
that machine. However, I can't get another AMI (RH6) also to 
successfully query the DNS server I setup. I've verified that UDP 53 is 
open in the security group and I can ping the DNS server from the other 
host but any lookups just say can't connect to any DNS servers.

Is there a step I'm missing?
