Cisco VPN Client & Windows 8 (32bit & 64bit) - Reason 442: Failed To Enable Virtual Adaptor - How To Fix It

Written by Administrator on . Posted in Cisco Services & Technologies

The Cisco VPN client is one of the most popular Cisco tools used by administrators, engineers and end-users to connect to their remote networks and access resources.

With the introduction of Windows 8, Cisco VPN users are faced with a problem – the Cisco VPN software installs correctly but fails to connect to any remote VPN network.

Note: Windows 7 32-64bit users dealing with the same problem can refer to our Troubleshooting Cisco VPN Client - How To Fix Reason 442: Failed to Enable Virtual Adapter article.

When trying to connect to a VPN network through a Windows 8 operating system (32 or 64 bit), the Cisco VPN client will fail to connect. As soon as the user double-clicks on the selected Connection Entry, the VPN client will begin its negotiation and request the username and password.

As soon as the credentials are provided, the VPN client shows the well-known “Securing communications channel” at the bottom of the windows application:

After a couple of seconds the Cisco VPN client will timeout, fail and eventually the connection is terminated. The user is then greeted by a pop up window explaining that the VPN failed with a Reason 442: Failed to enable Virtual Adaptor error:

Note: It’s always a great idea to have the latest Cisco VPN client installed. Users can download the Cisco VPN client for Windows, Linux and MacOS operating systems by visiting our Cisco Tools & Applications download section.

 

Introducing the Fix – Workaround
