Cisco VPN Client version is not starting

Dear all,

I am using the Cisco VPN Client version on Windows 7 Enterprise edition and some weeks ago, when I reboot my system, the Cisco VPN Client is not starting anymore.

I got the following error message: "Error 56: The Cisco Systems, Inc. VPN Service has not been started. Please start this service and try again."

I've already tried to add the cvpnd.exe service manually, no success. Windows return I cannot accees the application. I'm on the administrators group.

The only option i found is unistall the Cisco VPN Client and reinstall it again. It's so painfull.

Please help me out!

Thank you,

Re: Cisco VPN Client version is not starting

i have the same problem. First, I was using v5.0.05 and it worked fine with Windows 7 ENterprise, until one day when I get error:

Log Name:      System
Source:        Microsoft-Windows-SharedAccess_NAT
Date:          15.6.2010. 23:36:02
Event ID:      31004

The DNS proxy agent was unable to allocate 0 bytes of memory. This may indicate that the system is low on virtual memory, or that the memory manager has encountered an internal error.

I couldn't connect to any site. I get auth prompt but I couldn't connect.

Then, I uninstalled it and install the latest version. Now, I'm expiriencing same problem you do.
