Cisco VPN Client & Windows 8 (32bit & 64bit) – Reason 442: Failed to enable virtual adapter

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. This article shows how to fix the Cisco VPN Client Error Reason 442: Failed To Enable Virtual Adapter when trying to connect to a remote VPN Gateway or Router from the Windows 8 operating system (32bit and 64bit).

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.

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:
