Hi,
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.
And what does this has in common with the thread you've replied to?
Jul 12 11:17:44 ns1 named[14948]: client 178.33.222.134#38772: query

Looks like rankstel.net is delegated to two nameservers
(see dig ns rankstel.net @e.gtld-servers.net.):
ns1.ranksitt.net. (which refuses to answer for it) and
ns1.rankstel.net. (which times out).
So, rankkstel.net is broken, you cannot do anything with it.
Jul 12 11:17:49 ns1 named[14948]: client 69.73.138.12#55591: query (cache)
'era.com.bd/MX/IN' denied
And era.com.bd is delegated to ns2.ranksitt.net., ns1.ranksitt.net. and
dns.bankasia.com.bd.
And I see three different answers from those servers. Only
ns2.ranksitt.net seems to be configured correctly (But I haven't dig any
deeper).
Note, I've not tested it deeply, so it might be wrong.
Regards,
Torinthiel
