|Thanks for answering. I was curious.|
One of the reasons I don't wish to do that is security. Using the default port is kind of like sending an open invitation
Logical and I understand totally. However, knowing something is listening on port 3389 and even being able to connect to it, isn't the same thing as knowing the login information necessary to get all the way inside the LAN once you've connected to whatever is listening on that port.
Also, doing things your way means that at least two computers would have to be turned on for this.
No matter which way you slice it, if you wish to connect to a computer remotely, it has to be on.
So regardless of which way you do it, you still need to have those computers on unless the NIC's on them are WOL capable. If they are WOL capable, then you'd have to connect to one computer that's been left on in order to send the magic "wake up" packets to whichever other computer(s) you might wish to connect to. I don't know if you could send that magic packet through the router directly.
And, while in session, no one else would be able to use the computer I initially accessed
Very true. While I do this all the time at home, knowing full well nobody there is trying to use my computer, this isn't necessarily going to be true for a work environment.
Obviously, I have no intention to make things complex, but I am looking for the best (and comfortable) solution. My guess is, other than the method you're using, the only option left is to change the listening port on every computer, while reconfiguring Windows built-in firewall settings.
Actually, there is another alternative. You could use 3'd party software to connect remotely. We're using a product called TeamViewer here at work and the guys in the PC department like it a lot. It connects through a 3'd party server (both ends have to have the application up and running in order to connect) so you don't even need to play with firewall settings to use it.
It might be worth it for you to look into something like TeamViewer.
It matters not how straight the gate,
How charged with punishments the scroll,

I am the captain of my soul.
