Tony from Carmel from Carmel #3 | Friday, March 30, 2007 6:49 PM Didn't work but rebooted my computer and the problem went away. Steve from Minneapolis #4 | Friday, May 4, 2007 5:30 PM Nice - works to correct the same issue when running Windows on a Mac (restart the Cisco VPN Service). Jason McCarty from Canada #5 | Monday, May 7, 2007 11:08 PM This did not work for me. I've gotten this error ever since I installed the VPN from cisco. I have the 4.9 version as well. What else might I need to do? Anders from RTP #6 | Tuesday, May 8, 2007 9:50 AM Yep, a friend of mine pointed that out and I have since confirmed it. Apple's new security update kills CiscoVPN when using dialup adapters. I don't yet have a work-around though I hear it is an issue with Apple
