Ok, so i'm having trouble connecting my air and desktop. what is working: desktop has full access through user login on the air. air finds my pc, but can only log on as a guest, reducing access to public folders, I want to log on as a registered user but it simply wont accept me. My account on the pc has no password, could this be part of the problem? Cant seem to find where to delete this, but i fixed it, the fact that the pc didnt have a pw was the problem.
