Hi sparky_a:

 

How are these machines connected.  Does one machine have a wired connection to the router, and the others connect wirelessly, do they all connect wirelessly?  Does your sister have your machine added to a work group?  Is sharing turned on in any of the Windows settings.

 

There is a lot of information that we are missing.
