Here is the issue.

I have an HP dl380 G3 server with dual nic's. It is running windows 2003.

Randomly NIC 1 stops responding, even thou on the server it says its up and running just doesn't recieve or send any packets. I can disable it and enable it again, and boom it works. But its getting really annoying when about every 7 to 16 hours it stops responding for some odd reason.

Nic 2 is used for LAN and its always working and never has this issue. Its how I rdp in everytime.

I updated everything, reinstalled all the drivers to make sure everything was up to date. I have tried everything I could think of but my head is numb. Especially after being woken up almost every night for the past 5 days to just reset a network adapter.

sounds like it could be electrical noise "spiking" the protection circuitry and shutting down the socket.
