Hi, George! Thanks for taking the time to try to educate me on this. I really appreciate it!!!!
I guess what I still don't understand is, if I want to connect to a PC that has the IP address of 192.168.0.1, and follow the documentation for the VNC viewer and type "192.168.0.1" as they show in the example..... how does VNC know which computer I want to connect with, of the gazillions that have this IP address? How do I specify to VNC exactly which computer I want to connect with? If, as in the example, I type in "192.168.0.1" as the server, to me this is somehow like sending a letter off in the mail addressed to John Smith and not specifying any more detail. Thanks for your patience.... :-) Mary --- "G.
