I currently have a domain controller which handles all DHCP and DNS. The DHCP works just fine and the domain controller itself can use the internet with no issues. However, PCs that are part of the domain are not able to use external websites, only internal.

Does anyone have any way I can solve this issue? Thank you

Is that lookup from the DC or a domain PC? Please can you edit and add the results of a netstat -rn from a domain PC? – Paul Dec 16 '12 at 10:57
Could you add the nslookup from the domain PC as well? It all looks right so far. – Paul Dec 17 '12 at 12:13

It sounds to me like the server isn't using / it's local ip as the DNS server, whilst other machines are working fine.

Anyway, a basic test to do:

From the dns server, type:

nslookup and see what it says under default server.

Anyway, in the DNS server management console, make sure that either the root servers are turned on, or you have it set to forward queries to your ISP/favourite DNS provider.
