If you really mean this, then what are the devices that "are hidden
behind desks and boxes ... in the office"?
If, as seems more likely, there's some sort of router back there, and
your colleague is using wireless, then there's likely to be an
unused ethernet socket on it which you should be able to connect to
your colleague's computer.
If that computer doesn't have one, does it have a plain old parallel
port? Bit old-fashioned but there we go.
Cheers,
