I'm very familiar with this product, if you have any questions. In fact, i'm going through it now to visit the grumble from remote. I was on the beta team for version 10.5 of the product, and have been using it for about 10 years.
We have it installed on our pos computers, on our wizard, at each of our home office machines, on our laptops, and at my other jobs. We can jump back and forth from any machine to any other machine, to grab a file/back up info via the internet/provide support/work up a quick price for a client or from home.
Basically, it extends your machine's keyboard/mouse/monitor to a remote location and lets that remote location take control of your machine. (you will be able to see them typing and moving the mouse, if watching). You can also chat/type with the remote person. We use it to back up our quicken and pos program & data folders every week, from the office to home. (we also do daily data backups on site)
pcAnywhere answers by modem, or through the internet via default ports 5631 and 5632. If you're running a router or firewall, you'll have to open and forward these ports to the internal machine. (I can help with that process if there are any questions)
This program is generally best when the host machine has a DSL or cablemodem. pcAnywhere doesn't just let anyone into your computer. It has security encryption, and requires a user name and password for access.
Windows XP has something similar built in, and some CMC companies use a product called LAPLINK - which has similar functionality.
Don't hesitate to ask if you have further questions
