    Loopback Adapter Installation on Windows Server 2012

    Posted on by Russell Smith in Networking with 1 Comment

    How do I install the loopback adapter in Windows Server 2012?

    While there is a tendency for vendors to assume that we are always connected to a network or the Internet, there are occasions when network connectivity is not available but we’d still like to use an application that requires an IP address. One example is Hyper-V, which when used without a network connection has limited functionality if there is no IP address available on the host.

    Install Loopback Adapter

    Microsoft’s loopback adapter can be installed to provide a virtual network connection and IP address. Here’s how you do it.

    • Logon to Windows Server 2012 as a local administrator.
    • Right-click the far bottom left of the Taskbar, over the Start charm when it appears, and select Device Manager from the menu.
    • In the Device Manager window, right-click the server name and select Add legacy hardware from the menu.
    • Click Next on the welcome screen of the Add Hardware Wizard.
    • Select Install the hardware that I manually select from a list (Advanced) and click Next.
    • Under Common hardware types, scroll down the menu, select Network adapters and click Next.
    • On the Select Network Adapter screen, select Microsoft from the list of manufacturers.
    • Select Microsoft KM-TEST Loopback Adapter from the list of network adapters on the right and click Next.

    Loopback Adapter Installation

    • Click Next again to confirm that you want to install the loopback adapter.
    • Click Finish once the installation has completed.

    Configure Loopback Adapter

    Now that the loopback adapter is installed on the server, you can configure it via the Network and Sharing Center.

    • Right-click the network icon in the bottom right corner of the desktop Taskbar and select Open Network and Sharing Center from the menu.
    • In the Network and Sharing Center window, click Change adapter settings.
    • In the Network Connections window, right-click the Microsoft KM-Test Loopback Adapter and select Properties from the menu.
    • On the Networking tab, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
    • In the Properties dialog on the General tab, configure IP address network and DNS settings as required and click OK.
    • Close the adapter’s Properties dialog.
