Prior to purchasing AC, I was told it should run with a VPN. My IT person set up a CISCO PIX firewall VPN and AC won't work from my laptop at my 2nd office location. AC tech's tell me that dont know why. I had a 2nd IT guy come in, he set a tracer and found that AC runs from Port 445 and opened up the port but had to set up a virtual driver (I think? I hate computers) Anyways, eventhough AC runs from the laptop, it takes 5-7 minutes just to load it and runs at a snail's pace. AC techs can't help. I had to load Remote Admin and purchase a 2nd computer so that I could log in on one computer while my receptionist is on another. Anyone try a VPN not the XP VPN? HELP!!! I've been told by several IT engineers that the XP VPN is unstable and not secure enough for vital information such as patient's charts with the info in their demographics, especially. I would really appreciated any input. Thank you.
