Solved Cisco VPN Client cannot connect - Error 51 Posted on 2007-06-28 Cisco VPN 1 Verified Solution 7 Comments 12,756 Views Last Modified: 2013-08-02 I am unable to initialize the Cisco VPN client software on windows 7 a Windows XP laptop. When I click on the shortcut to intialize the program, it returns an error which reads: "Error 51: Unable to communicate with the VPN subsystem Please make sure that at least one network interface is active and has an IP address and start this application again." I have unintalled the client software and then re-installed, I have installed a newer version of the client software, and then uninstalled cisco vpn service and re-installed the original version of the Cisco client software, and nothing has corrected this issue. At one point in time, the client software ran perfectly on this laptop. Without any knowledge of any changes to the system, it just started this error message a week ago and I cannot get around it. Please advise on this - it is a critical issue dealing with a local law enforcement agency. 0 Question by:nsdhouston Facebook Twitter LinkedIn Google LVL 5 Best Solution byjkittle99 More than likely - you made the right choice.

Don't know if you're dealing with a "windows thing" or an environmental issue - firewall, etc. Any software firewalls configured on the box that might be doing something weird? Any changes made to the system that you can tell us about? 0 Message Author Comment by:nsdhouston2007-07-02 Well, I gave up on this issue and decided to reload the laptop altogether. I

Sorry! This is for client 4.0.2 for XP, but I think the same applies.
