I have been trying to set up VPN on a users PC. They have Windows ME and a cable modem. When I download the checkpoint software and install it , they lose internet connectivity. I never get to the point of setting up the site. It's an RCA cable modem and I did update the driver but that made no difference. As soon as you remove checkpoint, connectivity returns. I installed VPN on a ME laptop with dialup modem, and had no trouble. I'm baffled!
