Windows Server 2008 R2 - Hyper V has 3 VMs and randomly (sometimes days apart or weeks) a VM will lose the network connection. By lose I mean that a limited connectivity message appears over the VM's NIC. The problem goes away if the VM is rebooted (i haven't tried to disable and re enable the NIC, I'll try this the next time it happens).
I can't find any error logs on the hyper v server or VM that points to anything when this issue happens.
The hyper-v has 2 NICs one is used as a bridge for the virtual switch for the VMs.
Any ideas on tracing this down more?
