Windows 8.1 and Cisco VPN – Error 56

July 19, 2013 5 comments

After upgrading my OS to Windows 8.1, I ran into the following error dialog when trying to launch my Cisco VPN client:


Cisco VPN Error 56


I went to my Services and tried to start the, “Cisco Systems, Inc. VPN Service” from the Microsoft Management Console (MMC) but I received the following error:

Cisco VPN service error


Next, I went to Windows Event Viewer and found the following error under the System category:

Windows Event Viewer


Now that I had a better description as to why the service wasn’t working properly, I decided to perform a quick search and see what I could find.  The following two links were exactly what I needed:

I went back to the Services using MMC and found the “Internet Connection Sharing (ICS)” service and stopped the service and also changed the Startup type to Manual as shown below:

Internet Connection Sharing (ICS)

Once I made that change, I simply went back to the “Cisco Systems, Inc. VPN Service” and tried to start it again.

That is all it took to get my Cisco VPN client working again.  I am not really sure why this is happening but hope this helps anyone else who runs into the problem as well.

Windows 8 and Cisco VPN

If you ever need to get Cisco VPN working with Windows 8, you might need to perform the following registry hack.  When I first installed Cisco VPN and tried to get it to work on my Windows 8 Lenovo Yoga laptop, it would never allow me to connect. Here is the error message I get:

Secure VPN Connection terminated locally by the Client.
Reason 442:  Failed to enable Virtual Adapter.

Here is a screen shot of the error dialog as well:

Failed to enable Virtual Adapter

Here are the steps that I had to take to get my Cisco VPN client ( for x64, for x86) working:

  • Open Registry editor by typing regedit in Run prompt
  • Browse to the Registry Key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CVirtA
  • Select the DisplayName to modify, and remove the leading characters from the value data up to “%;” i.e.
    • For x86, change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to “Cisco Systems VPN Adapter”
    • For x64, change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to “Cisco Systems VPN Adapter for 64-bit Windows”
  • Try connecting again

Hopefully, this helps anyone else out there that is running into issues with using Cisco VPN on Windows 8.
