How to fix Reason 442 error using Cisco VPN Client in Windows 7

Among all computers I have installed Cisco VPN Client, my Windows 7 is the only one that had the problem connecting to the remote VPN server. I kept getting this Reason 442 message telling the connection terminated locally by the client pretty much every time when I wanted to use it.

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

It was really annoying because if I wanted to use it at home I would have to fire up one of my Virtual machine and use the VPN client from there. I always thought it might just be my computer that has got too many things loaded and didn’t want to cooperate with Cisco until I found the fix today. And the fix was so easy that I wondered how come I never thought about it.

It was all Internet Connection Sharing (ICS) service‘s fault. If you had this same problem as mine, simply:

1. Stop Cisco Systems, Inc. VPN Service;

2. Stop and disable Internet Connection Sharing (ICS) Service;

3. Restart Cisco System, Inc. VPN Service.

Launch VPN Client again, and the problem is gone.

Note that I am running Cisco Systems VPN Client version 5.0.07.0290 on Windows 7 Professional 64-bit edition.

  1. I am running Cisco Systems VPN Client version 5.0.07.0440 on Windows 7 Home Premium 64-bit edition. AND IT’S NOT WORKING ): could you please help me? I did exactly as you did.

  2. GREAT, except that I need to have ICS working too – I sometimes get it to work, and other times, well – still looking to understand the issue BUT simply saying disable ICS aint it

  3. I’m using Cisco 5.07.0440 and the proposed solution did not work for me. Any hints how to overcome the problem?
