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 services.msc, it got killed in a few seconds after thus you can not run the client.
Update: thanks to
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.
Posted 25 May 2008 at 4:47 pm ¶Hi Zhigang, yes you must uninstall the Cisco client first.
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.
Posted 27 May 2008 at 4:00 pm ¶Zhigang Wu, you are a genius!! I have had this issue with the Cisco client for weeks. I just tried you solution (disabled ICS on my wireless connection) and it worked!!

Posted 30 Dec 2008 at 8:56 am ¶MAKE SURE THAT THE SERVICE RELATED TO CISCO VPN IS UP AND RUNNING IN *SERVICES* IN THE BACKGROUND.
Posted 29 Jan 2009 at 5:37 pm ¶First of all, thanks to Zhigang Wu. Initially I had the same issue then after looking at this blog, I tried disabling Internet Connection Sharing (ICS) service but the problem was still there I had no clue what to do. But after doing some research I found that on my desktop “Cisco System VPN Client” was blocked under “Internet Applications” tab in McAfee firewall settings. Thats it!! I unblocked it and Voila it worked. This worked for me under McAfee environment and I am sure its the same firewall thing for any other anti virus s/w users. All the very best.

Posted 13 Jul 2009 at 11:48 pm ¶I have tried changing the Cisco VPN Service to Manual and then starting. I’ve also tried disabling ICS. Still, I keep on receiving the same Error 56.
Anything I can do?
Thanks
Posted 26 Jul 2009 at 2:07 am ¶Thank you very much for the easy sollution of the VPN problem.
Posted 28 Jul 2009 at 3:44 am ¶After stopping Internet sharing service and start Cisco VPN service it worked fine for me to start the VPN session. This summer I set up shared inetnet on my computer and that’s why the sharing Internet service was started. That’s why I never had had this problem before.
Shoot, I disabled my ICS service a long time ago, but it still can’t work on my vista sp2.
Posted 17 Aug 2009 at 10:08 pm ¶Thanks Pal…
Posted 27 Aug 2009 at 2:59 am ¶my antivirus provider advised me to uninstall all vpn software because according to them it's a conflict and their program will not work if there's a vpn.is this true?

Posted 03 Jan 2010 at 1:52 pm ¶computer keeps freezing
I also tried this but without success.. There are other clients to connect to the VPN network.. Take a look at what I found: http://blog.hebbink.com/post/2009/12/20/Error-5...
Posted 10 Jan 2010 at 5:27 pm ¶Real facts for error 56:
Posted 23 Feb 2010 at 1:55 am ¶1) the service vpn cisco broken;
2) create the service again;
3) sc create CVPND binPath= “C:Program FilesCisco SystemsVPN Clientcvpnd.exe” depend= “TCPIP” description= “Cisco System, Inc. VPN Service”
4) go to the control panel and fine the service to work
but excuse me but in the services on my pc i haven't CISCO or VPN service why?
Posted 09 Mar 2010 at 4:56 pm ¶Hello, fabio0025.
1) So, if your CISCO VPN was instaled, and, the service: “Cisco System, Inc. VPN Service”, not exists;
2) Go to the command line: win -> start -> run -> cmd;
3) Execute the command: sc create CVPND binPath= “C:Program FilesCisco SystemsVPN Clientcvpnd.exe” depend= “TCPIP” description= “Cisco System, Inc. VPN Service”
4) Go to the Control panel: win -> start -> control panel -> administrators tools -> service -> CVPND, and fine the properties to the service work, ok.

Posted 10 Mar 2010 at 2:14 am ¶Hello, and thank you.
Posted 10 Mar 2010 at 9:45 am ¶I did what you said but if the folder is created on cvpnd.exe in Services there is the service to start …
Thanks Carlos, your solution worked for me.
Posted 02 Apr 2010 at 5:17 pm ¶For some reason the original service had vanished from my system.
Perfect, this save my life… this error appear on the President's Laptop..
I adjusted the command line, I changed description to DisplayName and add the option start=auto
Very thanks!!! Eduardo (BR)
Posted 25 May 2010 at 12:52 pm ¶Two comments only:
1. I had to use a slightly different syntax (more parameters):
C:Program FilesCisco SystemsVPN Client>sc create CVPND binPath= “C:Program F
ilesCisco SystemsVPN Clientcvpnd.exe” type= own type= interact DisplayName= “
Cisco VPN Service”
2. I had to run the command as Administrator
Apart from that, really useful.
Thanks a lot for sharing!
