In windows 2000 on a domain DNS settings won't allow me to have internet and group policy at the same time

I've got many useful answers here on yahoo answers from you guys. Thank You. My windows 2000 network is working except one thing. When I log in the domain from the workstation I want windows to load the custom group policy settings that I created in active directory. I can do that easily IF I repeat IF I set the DNS IP address in tcp/ip settings to the one that I'm running on the server. I'm also using internet sharing on the server and I'd like to access the internet from the workstation. TTT it only works if I change the DNS settings to my router's ip address. So I either have gpo applied OR have internet because each feature requires it's own DNS setting. How can I have both? I have to have GPO applied so I can restrict the user's environment and I have to have internet on the workstations. I have 2 NIC in the server by the way and I enabled the internet sharing on the NIC that is connected to the router that is the internet (if this info help). Thank you for your help you guys.
