On the PC that can connect to the internet, go into network properties, tcp/ip, advanced, there is a DNS tab, you may or may not have settings in there. If not, go to a dos prompt, by clicking, start, run, then type, cmd. In the dos window type ipconfig. Then you should see two DNS entries. Type those into the second computer, where I mentioned above. That should solve your surfing problem. The other thing the second pc will need is a default gateway. In your case the default gateway will be the internal IP of the machine with two network cards. Hope this helps. Ashley
