Cisco Vpn Client Error 51 Windows Xp
Cisco VPN Client Comments By Rob Griffiths, Macworld Oct 17, 2008 12:57 PM One of the most-used programs on my Mac is the Cisco cisco vpn client error 51 windows 8 VPN Client, which is what I use to connect to Macworld’s VPN when posting articles such as this one. (OS X’s built-in VPN client also works, but it also logs me out of and then back into iChat every time

I connect or disconnect from the VPN. The Cisco VPN Client doesn’t have this annoying problem, so I use it instead.) While the Cisco VPN Client works well most of the time, sometimes when I try to launch the application, I’m greeted with this error message in place of the usual connection dialog: Error 51: Unable to communicate with the VPN subsystem. Please make sure that you have at least one network interface that is currently active and has an cisco vpn client error 51 unable to communicate with the vpn subsystem IP address and start this application again. The error is clearly incorrect, because my machine’s networking capabilities are otherwise fine—I can browse the net, send and receive e-mail, and connect to other machines in the house. I don’t get the error message all the time, and I don’t really know what causes it. It does seem to happen more often if I’ve slept and woke the machine, or moved it from one defined location to another, but even then, it’s not predictable. All I know for sure is that it’s annoying, because (until recently) the only fix I was aware of was to reboot the machine. One day, after probably the second or third time I’d restarted my machine, I decided there must be a better solution, so I went digging to see if anyone else had already found one—and they had. As detailed on the linked site, the solution is a relatively simple command that you execute in Terminal (found in Applications -> Utilities). After discussing the Terminal command with a friend, he came up with an even simpler version that works just as well: sudo SystemStarter restart CiscoVPN You’ll need to be an administrative user to run this command, and provide your admin password when asked. You won’t see any output from the command; the Terminal prompt will return when it’s done. After using the above command, the Cisco VPN Client should run without any problem

to tech-support, finding out that the error isn't explained in the manual and a re-installations we found the following to error 51 unable to communicate with the vpn subsystem mac work: disable the Firewall and Virus-software (McAfee in that case; make sure your machine is still behind another firewall, e.g. your routers' firewall), go to the Control Panel > Administrative Tools > Services. http://www.macworld.com/article/1136208/ciscovpn.html Then stop and restart the "Cisco Systems, Inc. VPN Service". The startup setting should be set to automatic BTW. I still don't quite understand why this works (Shouldn't the client communicate with the service using named pipes? Shouldn't the firewall be irrelevant for the startup of the client?), but hey… Please leave a comment if that worked for you; or whatever workaround you found. Thanks.

It had way too many protocols installed, tunnelling hooks in it, it wouldnt get on the net. I removed bunches of those, but it still has windows firewall and mcafee AV/sysprotect running. I'm going to try and run zonealarm on it. Then I'll try putting in a router beteen the cable modem and laptop. Bumika says: October 1, 2007 12:01 pm at 12:01 pm (October 1, 2007) I had the same problem using another security software. It blocked cvpnd.exe and logged a boep (buffer overflow exploit prevention) event. McAfee AV has a similar feature so that I think its boep blocked your instance of Cisco VPN client.
