are you using a 'crossover' cable for this? you can't patch two NIC' directly together with a regular patch cable, it has to be a crossover cable that has Tx wired to Rx and visa versa. Also, I've had mixed results using crossover cabling with 1000baseT gig ethernet
A John rightly points out, you need a 'crossover' cable when not using a hub or switch. It's likely a good idea to have a few crossover's in house. On the chance you're not familiar, this link may prove helpful
