Jonathan, It sounds hardware specific to me. Is this a new install or a new problem? If it is a new problem, then what has changed? Is the NIC in question onboard? What hardware are you using? Brands, MoBo, NIC, etc... If I were you, I would remove or disable the NIC and stick a tried and true old school 3Com NIC in the server and try that.
