My mid-2010 MBP is showing that it is trying to connect to a windows machine which resides on my network. I have never setup sharing, or connected in any way, between these 2 machines. I am wondering: 1). Why is my machine attempting to connect to the windows machine? 2). How do I stop what appears to be this continuous attempt to connect? 3). I want to configure my MBP such that no machine, osx or otherwise, can connect to it, unless I specifically allow it to happen. I say this because until I happened to notice the attempting connection going on in finder network view, I was not even aware it was happening. So I am concerned that in the same way, invisible to me and my permissions, some other machine may be trying to connect to my MBP - and might even be successful for all I know. Thanks for any help. EDIT: As an addendum, I know that windows machine has iTunes on it. Something to do with that maybe?
