Running the GoToAssist connection wizard should resolve your problem. If there is a way to connect around the firewall, it will find and store those settings for the current user. In my case, this solution did work, but we had to run the wizard again each time a new user logged onto the same PC.
You can find the wizard at
http://www.gotoassist.com/wizard. Just save it to your desktop, run it, and follow the prompts.
Let's hope Check Point fixes this soon.
