This is mostly a note for my benefit so that if I ever have this problem again, I know where to look.
I was using the VPN Client with no issues for months and then suddenly I kept getting the 442 error and after following all of the suggestions I found through search, I still couldn't resolve the issue. Finally I found this site here which solved my issue. I recently installed the new Intel my WIFI driver and it uses the internet connection sharing service to share the signal. Apparently that service and the VPN Client don't play nice with each other.
