I've set up a Windows 2012 HyperV parent with 2x Windows 2008 R2 guests (LOB requirement). The domain controller is on real steel and all are domain connected. All can be pinged and shares on the two guest OS's can be reached by UNC paths. The Network Sharing appropriate network discovery checkboxes have been checked. After some googlefu I've also now enabled and have running the Computer Browser service. Although no WINS server had been in the domain I even added one yesterday and configured the two server's NICs so that they use it; consequently they are listed as active reservations. The DHCP options for the network have been appropreately added. Of course I've installed the latest updates on all OS's and the vm's have the latest integrated components installed. The Parent is using NIC Teaming and on each vm I've drilling into the adapter settings to see if any related settings are there and now are. All hoops that I can imagine jumping through have been done.
What else? What stone haven't I turned over?
