A morning wish to all Gurus, especially to VPN specialists.
I am here today with an error to be resolved. I am running a server and serving many clients at different locations.
One of my client is receiving this error message on his PC.
 I have checked his connection settings and VPN client settings thoroughly but still the error reappears.
Â
Secure VPN connection terminated locally by the client.
Reason 442:Failed to enable virtual adapter.
Connection terminated on: Jan 9,2008 00:26:49 Duration:0 day(s),00.00.10
I think it may be due to Window's conflict because the user is having Windows Vista on his computer and may be Vista is causing this disconnection.
Now, when I formatted his drive and re-installed Win Vista latest version, I got the same error again, after configuration of VPN Client.
Does anyone have any idea  what the problem actually is?
VPN Client Connection Termination Error
Hi,
 Try following steps:
1) open VPN client and enable log so that when you connect to VPN next time error will be recorded in log.
2) Check whether log tells something about unsupported adapter with OS.
3) If so, Go to Network connections -> adapter Properties -> Check whether other adapter is installed and used for this connection. Â
4) Uncheck if any and press 'OK' .
5) Restart computer and try to connect again.
It should be fix your problem . If it doesn't visit Cisco site to get more support.

VPN Client Connection Termination Error
Greetings,
Â
The error you're getting has something to do with a duplicate IP address being detected by Windows. Let's try this for a work around.
Â
1. Go to control panel and open Network and Sharing Center.
Â
2. Click Manage network connections.
Â
3. Right click on the Virtual Adapter or VPN adapter and Enable it.Â
Â
4. Right click on the VPN adapter and choose Diagnose.
Â
5. When Windows Network Diagnostics is done, choose the second option, as shown as below .
Â
If the above steps did not work, open the Run console, type in CMD and code below and reboot the system.
Â
reg add HKLMSystemCurrentControlSetServicesTcpipParameters /v ArpRetryCount /t REG_DWORD /d 0 /f
Â
You may need to by pass the UAC by running CMD as an administrator.
