>I have a serious problem with my new Windows 2003. I installed a Server in my net with Windows 2003 Server for a Client and initially I got contact with my Internet without problem (during installation time). I am using COMCAST as my Internet provider. When I started to configure my DNS and my DHCP I lost any connection to Internet

>Additionally, I configured this Server for VPN connection and I didn't have problem testing with my LAN, but indeed, I don't know how it will work through the Internet while I am not connected.
