windows server network stopped around 3-4 hours

[aboyz]

This just happen recently. It was working for over 5 months. Anyone experience the virtual machine running windows server network dropped. I can get to it using the vnc console and it is alive. But the network doesn't work. futher I check the log and this is what I got? anyone know what it mean. I searched the forum and it is related to the intel nic card. I tried to implement the fix by disabling something on the nic but that didn't work. Anyone got a solution to this. I need to reboot the windows machine before the nic card start to work. I have follow this link and still same issues.
