little help connecting xbox to pc

[frequency]

hey dude....when i right click on my network connections on my desktop and choose properties, i have two local area connections. the one that is integrated in my motherboard is enabled and is functioning. the other one that is one of my pci slots is enabled but it says network cable unplugged. i think this is weird then sense i have my xbox connected with a crossover cable to that nic card. i guess windows xp hasnt recognized it and i know i have a crossover cable too.
