What error message do you get when you ping google.com?

If it's "host not found" then the DNS lookup has failed but pinging by 
IP address may still work (e.g. ping 216.239.37.99), in which case your 
underlying network is still working properly.

This is a very basic named.conf that just forwards queries directly to 
your regular nameservers, i.e. 24.93.1.118, 24.93.1.120, 24.93.1.247. If 
named is actually running then it should work very similarly to having 
those IPs listed as nameserver records in your /etc/resolv.conf

Can you ping those IPs when NM is running?

Can you do lookups using those nameservers directly?

$ dig @24.93.1.118 google.com

Can you do lookups using your own nameserver?

$ dig @127.0.0.1 google.com

This makes DNS lookups use your local named.
