how can I modify the drivers for a specific (any) NIC?

I want to force one way communication only, between two computers in MS windows 2003 server OS for开发者_如何转开发 security purposes.

I'm not sure if it supports turning on one way communication, but if you want to change the network adapter configurations I think INetCfg is the way to go:
