I have a network of 4 computers connected via ethernet (3 G5s and 1 macbookpro). All connect perfectly except one (a G5). I went into the sharing settings and noticed that "file sharing" was not checked, but when I try to check it, it won't let me.
The lock at the bottom of the panel is unlocked, so I don't see what is preventing me making this change, is there another lock elsewhere that I am missing? The other computers allow me to change these settings freely.
