After installing Windows Vista in our new storage testbed which uses the nForce 590 SLI-based ASUS P5N32SLI Premium motherboard, we noticed something odd. The network connection always dies after some time. There was no warning. No error message. The network connection just wasn't there.
At first, we thought the driver for the onboard LAN controller was not installed properly. But when we checked the Device Manager, both LAN ports were properly installed and in running order.
The only way to get the network up and running again was to reboot it. Even logging off and back in again didn't work.
