I am getting the same error. I'm not by any means a MAC guru, but have tried separate clients. Non of the five MAC users in my organization have been able to authenticate, and are all getting the same error:51 message.

Problem: Just got a new IMAC with System 10.5.4, now my Cisco VPN doesn't work. I had my files professionally transferred, vpn worked on my other IMAC, now it doesn't (Error 51). I downloaded vpnclient-darwin-4.9.01.0100-universal-k9.dmg, this version didn't work either (Error 51).

I have tried everything from repairing permissions to entering code in my terminal and still get the error. Any solutions to this frustrating problem? I have spent hours looking for solutions and rely on my VPN for work, so I need help fast!

Thanks to anyone with advice.
