in Mac OS X instead of the CiscoVPN software. Here's a guide that tells you how to convert cisco vpn error 51 windows xp from CiscoVPN to the native OS X client. If you are running

older versions) sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart (for newer versions) sudo kextload /System/Library/Extensions/CiscoVPN.kext and give your password when it asks. This will stop and start the "VPN Subsystem", or in other words restart the CiscoVPN.kext extension. Cisco seems to have problems when network adapters disappear and reappear, something that happens commonly in Wireless or Dial-up scenerios. Sometimes putting cisco vpn error 51 vista 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. 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? EDIT: The MacWorld guys came up with a simpler way to do the same thing: sudo SystemStarter restart CiscoVPN Posted by Anders Brownworth Monday, November 13, 2006 7:25 PM Tweet Comments (269) Jeff from Chicago #1 | Friday, March 23, 2007 6:53 AM Thanks for the tip - this worked like a charm. todd from boston #2 | Thursday, March 29, 2007 10:29 AM you the man - thanks!
