Dear Anad,
Thanks for the advise. Will follow these guidelines in future for sure.
Kindly let me know how can i fix this problem?
If its related remote domain NS issue, i shouldn't be able to resolve
the domain from anywhere continously. But i am able to resolve it from
internet without any issue. Problem is with only from our company BIND
DNS server only.
Below is the BIND GW Logs:
client 10.1.1.3#63581: view localhost_resolver: query:
www.dubaiairport.com <http://www.dubaiairport.com/> IN A +E
client 10.1.1.3#63836: view localhost_resolver: query:
www.dubaiairport.com <http://www.dubaiairport.com/> IN A +
client 10.1.1.3#62249: view localhost_resolver: query:
www.dubaiairport.com <http://www.dubaiairport.com/> IN A +E
client 10.1.1.3#64215: view localhost_resolver: query:
www.dubaiairport.com <http://www.dubaiairport.com/> IN AAAA +
Below is the sniffer logs:
3.351081 10.0.0.1 --> 213.42.52.75 DNS Standard Query A
www.dubaiairport.com <http://www.dubaiairport.com/>
10.761810 10.0.0.2 --> 213.42.75.79 DNS Standard Query A
www.dubaiairport.com <http://www.dubaiairport.com/>
Above sniffer logs clearly shows that we are not getting response packet
from www.dubaiairport.com <http://www.dubaiairport.com/> NS.

Babudheen
if i do understand this dns 213.42.52.75 is your dns server?
can you try localy (on the dns server) do a dig/nslookup/host?
it can be routing issue also.

Eliezer

It could be any number of things, and your vague question doesn't
provide any useful information for anyone to even begin guessing at the
problem. First of all, learn how to ask smart questions:

<http://www.catb.org/%7Eesr/faqs/smart-questions.html>
Next, try looking at the logs of your BIND server; perhaps it has logged
the reason for this resolution failure.
