You can find your computer's name on a Windows PC by opening the "About" menu. On a Mac, you'll find your computer's name in the System Preferences app, under "Sharing." Your computer's personal name ...

I need to take a running windows desktop box that's part of a domain, give it a new computer name, and then continue working on it (with the box having the new name), without having to reboot at all.

I have always just Ghosted them and then once I get them done, go and change the names. It's alot easier than building each one!
