Just so you know, there’s an Apple OS forum here on the Cow.
But I’m afraid I don’t have a good answer for you. Whenever I open our network connections, command-k, the window is always conveniently centered in one of the monitors. Regardless of where I move it, it always opens in the center of one monitor the next time. I’ve never had it open spanning the displays nor have I ever had it open way off to one side. However, Finder windows sometimes forget where they’ve been, especially if you have changed your monitor arrangement or the size of the display. Let’s say you had your monitor set to display a larger area. Maybe that network window was in the center of a larger display? Do you have two displays? Try opening that preference panel and just make some adjustments. Open your network connection, move it. Change your monitor size or arrangement back to normal. Try your command-k again.
Sorry, best I can think of this early.
