I setup a Hyper-V VM on Windows Server 2008 R2. The VM can access the Internet and can also ping the Domain controller and other systems on the network. The problem I am having is I cannot ping the VM or access any Rolls such as Remote Desktop Server from any system on the network, unless I turn off the Windows Firewall. All access is one direction. What are the correct Windows Firewall settings for a Hyper-V VM, because I don’t have this issue when I setup a standard (None VM) server?
