Hello Shoshannah
And welcome to Apple Discussions!
So you tried to manually start the Bonjour service? You can do this by clicking the
Start menu and then choose the
Run option. Then in the text box that appears type "services.msc". Next, locate the Bonjour service, right->click on it and choose "Start."
Or if you are or have already tried that and are receiving an error message about not being able to start, see this Apple support document.
