I have fallen in problem with my  dns server. Some times , some specific
domain can't resolve. From log report (/var/log/messages) i have given log
for that.

Jul 12 11:17:44 ns1 named[14948]: client query
(cache) 'rankstel.net/MX/IN' denied
Jul 12 11:17:45 ns1 named[14948]: client query
(cache) 'rankstel.net/MX/IN' denied
Jul 12 11:17:48 ns1 named[14948]: client query
(cache) 'rankstel.net/MX/IN' denied
Jul 12 11:17:49 ns1 named[14948]: client query (cache)
'era.com.bd/MX/IN' denied

If you advise, its useful for me.
