Problems resolving a domain name

Hi All,

One of our customers is trying to resolve www.ezexport.com using our DNS
servers (ns1.awalnet.net.sa and ns2.awalnet.net.sa) getting DNS timeout
messages. The customer can resolve the domain using other DNS servers.
Indeed I tested it using open DNS resolver and connection with a
different ISP and it resolves just fine. Here are the nslookup and dig
commands +trace output using our DNS servers and an open DNS server:

Nslookup debug set to d2 command output:

Default Server:  ns1.awalnet.net.sa
Address:  212.93.192.4

> set d2
> set type=any
> www.ezexport.com
Server:  ns1.awalnet.net.sa
Address:  212.93.192.4

How can I fix this problem so we can resolve this domain using our DNS
servers?
Any help is appreciated. Thank you.
