windows client request timed out

[Zelalem Fanta Woldesemayat]

Dear all,
I've configured BIND 9.9.4. as a cache only server on our DMZ so that it can serve as a DNS server for the internal network. Inside the DMZ zone the request time out is very fast and the DNS service resolves very quickly. But the problem is from the inside network. When I tried nslookup it gives the following message. Would you please help me to resolve this issue.

> google.com
Server:  [172.16.2.11]
Address:  172.16.2.11

DNS request timed out.
    timeout was 2 seconds.
