Procedure

  1. From the Hyper-V Server Manager menu, right-click Hyper-V Manager.
    A menu appears.
  2. Select Connect to Server.
    A dialog box appears prompting you to select the location of the virtualization server that you want to connect to.
  3. Specify the location of the virtualization server and click OK.
  4. Right-click the Windows Server 2012 R2 server and select Virtual Switch Manager.
  5. Create a new virtual network by selecting External from the list of options and clicking Add.
  6. From the External drop-down menu, select the physical network adapter you want to connect to.
    Note
    Note
    The physical adapter must be connected to the network and have access to the corporate network and the Internet.
    When you have Hyper-V running on Microsoft Windows Server 2012 or Windows Server 2012 R2 together with Broadcom NetXtreme 1-gigabit network adapters (but not NetXtreme II network adapters), you may notice one or more of the following symptoms:
    • Virtual machines may randomly lose network connectivity. The network adapter seems to be working in the virtual machine. However, you cannot ping or access network resources from the virtual machine. Restarting the virtual machine does not resolve the issue.
    • You cannot ping or connect to a virtual machine from a remote computer.
    This is a known issue. For details, see https://support.microsoft.com/en-us/kb/2986895.
