I quit VPN, then enabled each service and restarted VPN, to see which service was the apparent cause but I was able to re-enable ALL of them and still the VPN Anders from Cambridge, MA #240 | Friday, August 12, 2011 7:40 AM @Allen Can you post more of your system log right around the IKE FAILED message? Harry from London #154 | Wednesday, September 2, 2009 5:42 PM UPDATE: Yup, Cisco now seems to require you to be a partner company to access the VPN download, any suggestions? It finally occurred to me maybe I should try repairing file permissions.

Casey Woods from Calgary, AB #55 | Tuesday, February 19, 2008 12:03 PM Thanks! Well as it turns out its an architecture issue, because using kextutil told me that the compiled code does not support x86_64 architecture.
Once I changed it back to book with the 32 bit kernel it was not a problem. I get this error all the time and this fix always works for me. This worked beautifully, I am now booted into the 64-bit kernel and VPN-ing without Cisco's klugey code. Continued John from davis/ca/usa #18 | Monday, September 17, 2007 2:25 PM Oh yeah, and for good measure I turned off bluetooth.

If all else fails, you may need to reinstall your OS though I've never heard of things getting so corrupted that this is necessary. Dave from Ottawa, Canada #75 | Thursday, May 22, 2008 8:13 PM Brilliant! I have the 4.9 version as well. I cannot force all my customers to use anyconnect.

The Cisco VPN is crappy software. If you are running Cisco's VPNClient on Mac OSX, you might be familiar with (or tormented by) "Error 51: Unable to communicate with the VPN subsystem".
