Periodically I receive emails from people who find them and they start Virtual PC/Virtual Server, it reports that it was unable to initiate virtual networking on any network adapters.  There are two common causes of this problem, though they both seem to be related to something just going wrong during the installation of Virtual PC/Virtual Server's virtual networking:

Number 1: The Virtual Machine Network Services driver is installed but not enabled.  To fix this:

On a Windows XP system you’ll need to:

  1. Open the Start menu and click on Control Panel.
  2. Click on Network and Internet Connections and then Network Connections.
    If you are using classic mode you just need to double click on Network Connections.
  3. Locate your network adapter, right click on it and select Properties.
  4. Check the Virtual Machine Network Services entry and click OK.

On a Windows Vista system you’ll need to:

  1. Open the Start menu and click on Control Panel.
  2. Click on the Network and Internet and then Network and Sharing Center.
    If you are using classic mode you just need to double click on Network and Sharing Center.
  3. Click on Manage network connections, in the task list on the left side of the window.
  4. Locate your network adapter, right click on it and select Properties.
    You’ll need to approve this action.
  5. Check the Virtual Machine Network Services entry and click OK.

Number 2: The Virtual Machine Network Services driver is installed and enabled, but does not seem to be working.  To fix this you'll need to:

  1. Follow the steps for the first solution to get to the properties display for your network adapter.
  2. Select the Virtual Machine Network Services entry, and click Uninstall.
  3. Reboot the physical computer (this step is critical)
  4. Return to the properties display for your network adapter.
  5. Click Install…
  6. Select Service and click Add…
  7. Select the Virtual Machine Network Services entry and click OK.

A 90% of cases these two processes will get virtual networking up and running.

Cheers,
Ben

  • Darren and David Stower - cheers combination of both solved my problem. Just copies files from the C:\Program Files\Microsoft Virtual Server\Drivers\VMNetSv\x64 and pasted in windows/inf folder. Disabled and re-enabled the adapter and restarted virtual server service, and worked like a charm! thanks.

  • Hi,

    I have a even worst problem with the VPC, Nortel VPN and the wireless network on my Dell E6500 notebook running Windows 7. With VPC 2007 installed but not running at all, whenever I start the Nortel VPN V10.04.16 using the wireless connection, the Windows 7 will crash.

    I have tried on a couple of E6500 notebooks in the office and they all behaved the same. All these notebooks works fine as long as I don't start the VPN. Also, they works fine if I use a cable for LAN connection and start the Nortel VPN.

    I wonder if anyone has seen this before?

    Thanks.

  • My problem get resolved(XP SP2 and VPC2007), thanks to David Stowers.

    Step1.

    Manually copied the 2 INF files from the utility folder in

    C:\Program Files\Microsoft Virtual PC\Utility\VMNetSrv

    to c:\windows\inf

    Step2.

    Disabled the Virtual Machine Network Services driver.

    Enabled the Virtual Machine Network Services driver.(Will install the service again)

  • Thanks! This really solved the issue, I can keep working!

  • Hi guys! I faced the same problem with my windows 7 work pc trying to connect the emulator for debugging.

    I've tried almost everything found on Internet with no results.

    Finally watching the system event log I found an error which droved me at the following link support.microsoft.com/.../555395 where I found the solution!

  • On my Windows XP PRO with Virtual PC 2007 none of the workarounds/registry hacks/Virtual PC reinstall(s) suggested on the original blog post and the comments worked.

    In my case the solution consisted of uninstalling the driver of the network card (from Device Manager), then rebooting, and finally letting Windows XP detect the NIC, install the drivers and automatically rebuild any network bindings, including the binding to the "Virtual Machine Network Services".

    Because the drivers of the network card are already on the system, Windows won't ask for the path to the files. However, I'd recommend keeping a copy the drivers locally just in case Windows' plug-and-play subsystem is unable to reuse the drivers that are already in the system.

    As a side note, my new working network connection is now called "Local Area Connection 5" instead of the plain "Local Area Connection".

    Good luck.
