DNS external nslookup

Hi all

I recently installed a 3rd Domain Controller in my environment with windows 2k3 SP2. During the install and DCPROMO I used one of my existing DNS servers. After the install I gave the server an static IP address and pointed it to itself for the DNS and our other existing DNS server under TCP/IP properties.
I then installed DNS server with ADI which works internally but I cannot do an nslookup to any external sites such as www.google.co.uk as it returns with following error:

Default Server:  server.mydomain.local
Address:  10.10.0.4

www.google.co.uk
Server:  server.mydomain.local
Address:  10.10.0.4

DNS request timed out.
    timeout was 2 seconds.
*** Request to server.mydomain.local timed-out
>

Please also note that my primary DNS server is a windows 2000 DC. My intension are to transfer all FSMO roles from the 2000 DC to the new DC once the DNS side is working properly.

can someone please help.

Do you allow outbound access from that server on Port 53 UDP?

Have you configured Forwarders or are you using Root Hints (the default)?

Maybe you have a firewall that is blocking port 53 udp/tcp

Chris dent is right, you need to configure forwarders to your ISPs dns servers or failing that to Open DNS's servers on  208.67.222.222 and 208.67.220.220

Cheers omarfarid and Chris It was our firewall causing all the issues. Apparently this was our old email server on the same IP address and we had an old SMTP rule on that IP address to go out only.
