DNS not working

[Yogish]

Hi 
I made the changes susggested by barry, but still I was not successful in pinging either czar.brokerserver or schuh.brokerserver. I did restart the named daemon after changing the conf files, however there was no change in the response I got. Would I have to restart the entire server for it to work???. I would appreciate if there is something else which I can try.
Regards
