So I am assuming a logical solution to this problem (after looking at the provide tutorial; thank you very much, btw!) is that I should create a user name and password on my laptop for her to be able to log in, correct?
That still leaves the curious answer to why the ease-of-network-access is a oneway street... why does LAPTOP1 have full accessability of LAPTOP2, yet not vise versa?
Regardless, I'm going to try this and see if it makes any slight difference at all. I'll post a followup afterwards.
