Cisco seems to have problems when network adapters disappear and reappear, something that happens commonly in Wireless or Dial-up scenerios. Sometimes putting a system to sleep, disconnecting an Ethernet cable or simply reconnecting your wireless cisco vpn client error 442 will cause CiscoVPN to loose track of the network adapters on the system. Considering that CiscoVPN is typically used by telecommuters, this is an astonishing oversight on Cisco's part. The above hack should side-step all of these issues by causing the CiscoVPN to re-initialize. It makes one ask, why couldn't Cisco have just put the restart into their client? Or a better idea would be to not reinvent the wheel and use the existing IPSec VPN support in OSX! Am I missing something?

MacBook Pro, Mac OS X (10.6.4) Posted on Jul 21, 2011 12:12 PM I have this question too Close Q: Cisco VPN Client Error 51 message since upgrade to Lion All replies Helpful answers by Asatoran, Asatoran Jul 21, 2011 2:00 PM in response to buzz8976 Level 4 (2,525 points) Jul 21, 2011 2:00 PM in response to buzz8976 Are you using the software client from Cisco, or OSX's built-in VPN? In my experience, almost every operating system upgrade has needed a update to the VPN client software. Have you checked if there's a newer Cisco client for your office?That said, have you tried uninstalling and reinstalling the Cisco software? Also, OSX's built-in VPN client works for many Cisco implementations, so works for a lot of people. If possible, I recommend uninstalling Cisco's software an see if you can configure OSX's VPN. I'm currently using OSX's VPN to a Cisco ASA 5510 with SecureID authentication. With OSX 10.6.8 and 10.7.
