Your solution resolved my issue and made me happy. Just wow...what are the odds? Well as it turns out its an architecture issue, because using kextutil told me that the compiled code does not support x86_64 architecture.

CJ from maryland #206 | Monday, December 6, 2010 9:02 PM I'm receiving the VPN error 51 but i am using a PC not a Mac. In case anyone sees this as well, what caused the problem was the CiscoVPN.kext file corrupted, probably either on install of Snow Leopard, or update of a security patch to it--probably I quit VPN, then enabled each service and restarted VPN, to see which service was the apparent cause but I was able to re-enable ALL of them and still the VPN

In the console I get "Could not attach to driver.

You're right, it's not installed as a Startup Item. Does that mean trash, then repair permissions, then install?

As of May 2007, Apple has released an update that fixes this issue between Cisco VPN and OSX so now things work again as expected. Be thankful they even bothered to make it for Mac. I just cut and pasted sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart into my terminal. this contact form Thank you!

thank you Preston from Los Angeles / CA / USA #95 | Thursday, July 31, 2008 11:55 AM Thank you! The simple fix is to quit VPNClient, open a Terminal window, (Applications -> Utilities -> Terminal) and type one of the following: (for older versions) sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart (for newer versions) Only One Worked like a charm :) http://anders.com/guides/native-cisco-vpn-on-mac-os-x/ I am using MBPro 15" (64 Bit) Thanks All and Anders. Made a fixvpn alias for this, and it worked like a charm on Leopard 10.5.1 :-) Thanks so much! - Erik Balrob from A Kiwi in Utah #41 | Thursday, December

But no luck; my gut is telling me that the traffic on that Client IP address is not getting to/from my MacBook. Any changes made to the system that you can tell us about? 0 Message Author Comment by:nsdhouston2007-07-02 Comment Utility Permalink(# a19406785) Well, I gave up on this issue and decided and it started working again. There are three things to know: 1.) You need to ENABLE Internet Sharing to uncheck the ports.

Step 9: Perform a Clean Installation of Windows Caution: We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Error 51 problems. Carrie from Queensbury, NY #164 | Wednesday, November 4, 2009 5:27 PM Thank you Dan H and Anders! The above hack should side-step all of these issues by causing the CiscoVPN to re-initialize. Have you tried switching Wireless / Ethernet?
