VM's NIC fails after 10-15 minutes

Featured Replies

I have a windows 10 vm that boots up no errors and gets its DHCP reservation. I can RDP into it, but after a random amount of time, no more than 1 hour, it's connection fails. I can still see its connected to the router but it no longer responses to pings. I can reboot the VM and it still will not come back up. The only way to resolve it is to either reboot the whole unraid server or shut the vm down and boot it up much later. I am at my wits end trouble shooting this thing.

 

I have rebuilt the VM, verified all network drivers are updated, shutdown docker and all other resources, and tried muliple different network adapter types. Nothing changes the failure so far.

 

Below is the log from the VM and I don't see anything that is standing out and showing a failure. I am not sure what diagnostic file to link up here for better trouble shooting.
