Having trouble configuring my knoppix for LAN

[KNOPPIX_BOY]

Im running Knoppix off of a CD. I have a LAN Large LAN with T1 supporting the Internet needs of the whole lan. I configured my network cards to with subnet masks, ip addresses, and default gateways. I can view all the computers on my network it wont' let me access the T1 connection to surf the net. B4 I configured the Network card it would bring up the browser would bring up the error imediatly that it couldn't resolve the host name and now it says im online and it tries 2 resolve it for several seconds but bring up the can't resolve hostname error still the same. What do I need to config. to access the Internet?

Did you try to configure your network card? Click the penguin icon on the desktop > Internet/Network > Network card configuration.

Networkcard has been configured.
I would check /etc/resolv.conf.
