Cisco VPN reason 442 Solution

Cisco VPN Client reason 442: failed to enable virtual adapter on XP/Vista

This problem occurs because "Connection Sharing" is enabled for network connections. The solution is as follows:
1,Click "network connection"
2,Click "Cisco Systems VPN adapter local connection" and select "share" to remove the "allow other network users to connect through the Internet connection of this computer" item in/Disable Internet Connection Sharing;
3,Check the sharing options of several other local connections, disable them, and click your Cisco VPN Client to connect;

If you use the Vista system, when you connect to a new network (wired or wireless), the system will remind you to select the network location. There are three options: office, home, and public place, if you select a public place, the above modification will also result in a 442 error. In this case, you need to change the network location to office or home.
