dell 8400 internet connection problem!

I am having a problem with my dell 8400 at home. I have reformatted the computer with XP Media Center edition. However, when I went to the network connections, there was nothing but the 1394 connection available.

I am under the notion that it has nothing to do with the internet. More importantly, I cannot connect to the internet (the ethernet is plugged in)! Is there anyway to “create” the network connection that most computer seem to possess? Please help! thank you!
