I finally got it to work by installing version 4.0.3 and uninstalling Sygate Firewall and Symantec Client Security. I will re-install these today to see if I create the problem again. Just want to be sure and nail down the culprit. Also, interestingly enough I do not have the AssumeUDPEncapsulationContextOnSendRule=Reg_Dword in my registry. I found a script called adjustxpfw.bat that supposedly adjusts the firewall to allow you to have it on and run Cisco VPN software and not have it crash. This did not work so I tried the the uninstall and upgrade. That is when it finally worked. Go figure. I would guess that it does not like me to have both the MS Firewall and the Sygate Firewall installed at the same time. Thanks for all the suggestions.

Had the same exact problems, I ended up uninstalling the Cisco VPN software for now, I don't use it on my XP box, and haven't had a chance to spend anytime researching it and digging into the problem....

Has anyone else had problems running the Cisco VPN client software since SP2. The reason I ask is that I have it on my machine and since I installed SP2 it crashes my machine. It give me the dreaded BSOD and reboots. Anyone know of a workaround. All I could find on Google was to disable the Windows Firewall (which I did by default) and have the Stateful Firewall running in the Cisco client. I also am running Cisco 4.0.1. I need all the help I can get. I have remote users that rely on the VPN software and are running XP. If any of them install SP2, they and me will be hosed. Thanks again. Daryl S.
