Build a VM on Hyper V a couple month ago, windows server 2008 r2 standard. It has license applied and was fine with static IP since. Yesterday, the interface stopped working. The hyper v server is fine and there is an interface selected for the VM and network settings are still on that interface when you go into the VM from the hyper v administrator. What else could it be? I read there is a check box to share the mgmt interface for the hyper v server. I can't find that and the other 2 vms on the hyper v server are communicating fine. Thank you for your help!
