Well, considering that the netbios port is listed on the remote machine, and your laptops port are above 1024, I would guess that those connections originate from your laptop, going to the other machine, rather than the other way around.

EDIT

If there was an inbound netbios connection from the other machine to yours, it would show the netbios connection on your machine and the unreserved ports on the other end.

Do you use a domain name when loggin into your machine? like you log in as yourself into the mycollege.edu domain?

It could just be your machine connecting to the local master browser in order to populate the hosts which would get listed in network neighborhood/my network places.

I don't know off the top of my head what that connection would be exactly, but it does origniate at your machine.
