Disabling ICS as described by Nathan Le worked for me in Vista. No need to reboot.

turning off ICS did the trick for me (Windows 7) … tried almost all the other suggestions first with no luck. I guess error 442 is pretty generalized

Might I say that this forum is extensively helpful. But I suggest that maybe a good Registry Cleaner could help too. The thing about Registry Cleaners is that they constantly scan and clean your PC, preventing these and future errors like these from ever happening. I love them, and I strongly reccomend them.

I tried some of the first suggestions with no luck, then I saw Tim's suggestion and it worked great. I recommend everyone try this first,
I had this same problem start out of nowhere. After coming to this site and seeing some of the fixes, all I did was open C:Program FilesCisco SystemsVPN Client, right clicked on ipsecdialer.exe and vpngui.exe and clicked properties. I set both to run in xpSP2 compatibility mode and run as administrator. Problem was immediately fixed, no reinstallation was necessary and no DNE update was necessary. But yes I have to agree to let it run each time I start it.
