We have a couple of machines that were running Cisco VPN Client (5.0.01.06) and worked, but suddenly do not. On one machine we are getting Error 56: The Cisco Systems, Inc. VPN Service has not been started). I have tried several suggestions that I found online and none seemed to resolve the issue. I uninstalled the program and removed all registry keys and still no success. Others online reported having the same issue because of firewalls and anti-virus programs, but I removed all of those also (just to test). When manually start ing the VPN process, it starts, but within 30 seconds, stops automatically. I have tried rolling the registry back, but it doesn't go back before the initial install of the client. I have run spyware programs and anti-virus to make sure the machine is fine. It is only a few months old.
The second machine that was working with the VPN client and now isn't is a laptop, but his error is: Secure VPN Connection terminated locally by the client. Reason 442: failed to enable Virtual Adapter. Cisco suggested adding a registry key (HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f) which didn't work. I also tried Enabling the virtual adapter - repair - and disabling it again (along with complete uninstalls and reinstalls). I found and downloaded the latest version of the Cisco Client Version 5.0.02.0090. This didn't clear the error. This is a Gateway laptop with Windows Vista Ultimate 32-bit.
