Contact your system administrator.Note:If you see the message 'The installer was not able to start the Cisco VPN Client.', there is probably a compatibility issue. Unfortunately you can't directly copy the "enc_GroupPwd" into the "Shared Secret" field because it is "encrypted". Also, it would seem that Cisco is unable to respect conventions of not putting startup items /System/Library/StartupItems. I can connect with AnyConnect in Windows, but not Mac.

For VMWare not sure this is still an issue with VMWare 2.0 but the older version I just shut down like this: sudo "/Library/Application Support/VMware Fusion/boot.sh" --stop When you need VMWare, Anders from RTP #116 | Wednesday, October 8, 2008 9:55 AM Gavin: There is more to the Cisco VPN Client than the app in the Applications folder. (specifically, the directory /System/Library/Extensions/CiscoVPN.kext) I'm not happy that whenever I VPN I have to reboot into 32 bit mode, but luckily I don't need to do that often from the MacPro. Once I changed it back to book with the 32 bit kernel it was not a problem.
I don't yet have a work-around though I hear it is an issue with Apple, not Cisco. (I have nothing to back that up) I wish Cisco would just give up Sometimes putting a system to sleep, disconnecting an Ethernet cable or simply reconnecting your wireless will cause CiscoVPN to loose track of the network adapters on the system.
