RECOMMENDED: Click here to fix Windows errors and optimize system performance

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 troubleshoot 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 (32-bit and 64-bit).

With the introduction of Windows 8, Cisco VPN users are faced with a problem: Cisco VPN software is installed correctly, but cannot connect to a remote VPN network. When you try to connect to a VPN network using a Windows 8 (32 or 64-bit) operating system, the Cisco VPN client cannot connect. As soon as the user double-clicks on the selected connection entry, the VPN client starts the negotiation and asks for the user name and password.

This problem is usually due to the fact that the Cisco VPN adapter is not properly enabled when trying to connect to the hub.

Disable the ICS service

Unfortunately, the good old-fashioned method of deleting and reinstalling does not take you very far in this case, because the problem is not with the Cisco VPN client program, but with Microsoft’s Internet Connection Sharing (ICS) service.
