I have a server with 2 nics. I installed Hyper-v 2012 server (not windows server 2012, no gui) I am trying to set up load balancing. I have both nics in the same switch currently in trunk mode and no native vlan. I use the new-netlbfoteam command to create a team with both nics, I can then "set-netlbfoteamnic "Nic Team" -vlanid 4" so that its available to me with a DHCP or static address but as soon as I try to create a virtual switch it becomes unresponsive. My guess is that is due to it removing the vlan tagging I setup. if I add-netlbfoteamnic and set it for vlan 4, then set the IP I can ping it from my management computer but I just get an error "an error occurred while attempting to connect to server "xxxxxx" Check that the Virtual Machine Management service is running and that you are authorized to connect to the server."
