Macbook Pro and Macbook not able to connect to internet

Here is the deal. We have a windows network and all of the windows laptops connect just find to the network. It is a WPA2 Personal network. I can get both the Macbook and the Pro to connect to the access point without a problem. I am able to ping internal addresses without a problem. As soon as I try to get to lets say google.com it times out. If i open safari and wait for about 30 mins or so the page will eventually load. I have tried doing a complete reinstall of Leopard and still nothing. I am fully patched and updated to the latest version of leopard as well.

I also have checked the firewall to see if there is a ACL's that are not allowing it to connect. I have not found anything.

Access Point: D-Link 8200AP
Macbook Pro: AirPort Extreme

Any other details that you need to help me? Thanks,

Check the Mac's advanced network settings to make sure you don't have proxy set.

Also to eliminate the possibility that it is a DNS problem, can the Macs go to:  ?

If they can, you know the problem is DNS.

If not, what IP address are the Macs getting by DHCP?  If it starts with 169., then it is not a valid IP address.

No proxy, or DNS issue. I cannot navigate to that ip.

 Here is a traceroute of google.com.... THis tells me that I am leaving the network

It's a long shot, but try turning off IPV6.
