I don't need the mouse to work, just the keyboard. If I have to I can run Synergy to get the mouse functionality since I've established that it works fine on my systems.

Okay, on to the keyboard broadcasting. Using CMD, on my Windows XP box I was able to broadcast keys typed in notepad to two CMD windows. The closest thing I've had to success! But now to take it up a notch... How do I get the keystrokes to broadcast to a CMD window on my Windows 2000 box?

I was getting it to at least acknowledge that keystrokes were being made (using notepad, which I didn't realize wasn't functional, DOH) but after I was able to get the local versions of CMD to receive broadcast keystrokes on my Windows XP box, the Windows 2000 box now just repeatedly fails to establish a connection or reports that it is unable to bind to the UDP port.

I just discovered your tutorial page and am trying to use that to figure out a way around the issue, but if you have any pointers I would welcome them.
