![]() Select Microsoft Loopback Adaptor under Network Adaptor. Select No when prompted to select the hardware.Click Start > Settings > Control Panel > Add/Remove Hardware.Cases in which the computer is not on a network and does not have a network card, configure the TCP/IP to use the Microsoft Loopback Adaptor. But if you have the need for a test adapter, it is there in Windows 8.The ESRI License Manager requires TCP/IP installation. I’m certainly not implying that this is the only or best use of the loopback adapter. And when I’m in the office on my physical network, the virtual switch is bridged with the physical interface so all of my virtual machines can access the Internet. But since I’m not connected to any physical network, that’s not a problem. One other item I have to remember though is that in this scenario Windows considers the network public which means I need to turn the firewall off. Because the loopback adapter is bound to the Hyper-V virtual switch, my virtual adapter gives me network access from the host to the virtual machines and vice versa. If I am following the network paths that I’ve created correctly when I am disconnected from a physical network, the loopback adapter gives me a network interface with an IP address. I right-click the Network Bridge and assign it an IP configuration in a range that my virtual machines are expecting. In Network Connections, using the Ctrl key I click on the Hyper-V adapter and my physical network adapter, then right click and choose Bridge. However, one downside is that my virtual machines no longer can reach the Internet or my physical work network. You might be prompted about brief network interruptions so take that into account when making this change.Īt this point, this doesn’t change anything for the virtual machines and makes no difference when I’m connected to a network. ![]() In the Hyper-V management console click on Virtual Switch Manager and then selected my virtual switch.įrom the drop down list I select the loopback adapter and click OK. Now I’m going to connect it to the loopback adapter. Originally my Hyper-V virtual switch was connected to my Ethernet port. That’s when I realized the loopback adapter could help. Yes, the VMs can still communicate with each other, but I lose the ability (required in my case) to communicate between the host and guest. The challenge is that when I am out of the office, say presenting at a conference, if I don’t have a network connection, my virtual machine networking no longer works the way I need it. In my office I can easily reach virtual machines from the host and vice versa, which I need to be able to do. All my virtual machines are on the same virtual switch exposed to the physical network. I run Hyper-V on my Windows 8 laptop for development, testing and training. Which brings me to why I even bothered with this. Loopback adapter under Network ConnectionsĪt this point, you could configure the adapter’s properties to suit your needs. It shouldn’t take very long and not require a reboot.Īfter you finish installing, you should see the new adapter under Network Connections. Install Microsoft KM-TEST Loopback AdapterĬlick Next to install it. Select Microsoft for the manufacturer and scroll down until you find the Microsoft KM-TEST Loopback Adapter. Scroll down to the network adapters section and select it as I did in the screenshot above. Select the option to manually install hardware and proceed.
