I am facing packet lost issue with Intel 82579 LM network adapter.
Basically I have two system with same Intel 82579 LM adapter and both are working fine separately, but one I plug there network cables in switch, its start dropping the packets when I ping a system from other system,
I have also try with cross cable but unable to resolve the issue. On network only one system works fine, and when I stop working on it the other one starts work.
I have Google the problem and try many steps in registry and in advance setting of Lan adapters but no success.
I have an updated driver and my Windows platform is Windows 7 32-Bit.
