On some systems there is this problem with Cisco VPN service: cvpnd.exe must be excuted before you run the ipsecdialer.exe ( the GUI for the client ). But even if you start the service per hand in service.msc, it got killed in a few seconds after thus you can not run the client.
To work around this problem: Uninstall Cisco VPN in Windows Control Panel, then go to regedit and remove all the entries have Cisco term in them. Be careful, back up the registry with built-in export function of regedit first and do not delete somethings like “Franscisco”, ok ? Some entries can not be deleted, it’s normal, just F3 until you reach the end of the registry.

Thank you, good tips to fix a problem. Some time ago i’am fixing this bug as you write.
Posted 12 May 2008 at 2:12 pm ¶In your second paragraph, did you means I should uninstall the Cisico VPN and clear the Cisico terms in the regedit and then re-install this program again?
I remember I can run my Cisico VPN normally before updated the Visita SP1. I have no idea whether SP1 is the reason for this problem?
Hope you could send me an email to discuss, thanks a lot.

Some machines at my workplaces running Vista SP1 without any problem with VPN.
Posted 25 May 2008 at 5:19 pm ¶Lamnk, thank you very much. I have reinstall the Cisco VPN. it works. But sometime after restart computer, I will met Error 56 again. It seems when the computer connect the internet will occurs this problem oftenly. Did you have same experience?
Posted 26 May 2008 at 4:51 pm ¶No, i only encountered this error on two user’s laptops ( lucky, because you need to restart you computer at least 2 times to remove and install the software and THAT is a PITA with Vista ).
Posted 26 May 2008 at 5:33 pm ¶Lamnk, today, I have found the problem. Cisco Systems, Inc. VPN Service is killed by Internet Connection Sharing (ICS).
I stopped the ICS service manually and then I can run VPN client.

Thanks a million Zhigang Wu. I struggled with this problem for the better part of an afternoon last week. For me the VPN service was intermittently working but failing more often than not. Now it works all the time and life is rosey once again.
