A fix for 'Error 51' with the Cisco VPN Client
Authored by: chefhomer on Sep 04, '08 03:14:43PM

Yes - this fix does work great if you're an admin user - we've been using it successfully for a few years now. We also see this error occur a lot recently when switching between network locations and/or switching AirPort networks - most of the time if you quit the VPN client, 'Turn AirPort Off' from the AirPort menu - and then turn it back on and rejoin the airport network - the Cisco VPN Client can then be relaunched and will recognize the airport network interface. (which is the only workaround I have found for the non-admin accounts)

A fix for 'Error 51' with the Cisco VPN Client
Authored by: rfrost on Sep 06, '08 07:45:54AM

I maybe ran into an even simpler "fix," after getting the same Cisco VPN messa ge when connecting to my university's network. I simply opened the Network Pref Pane and clicked on the "details" or "advanced" button for whatever connection method was active, and that enabled Cisco to connect. My guess is that mt trick just forces an additional round of port-polling.
