Hmmm....leave it to a moron to point out my error. Hehe

My perspective in the statement about MS not messing up comes from this; Any attempt to connect to a network port that does not have software listening on that port will fail immediately.
This is how TCP/Ethernet works.
People get all paranoid about blocking access to ports that have no software running on them and all they do is announce themselves to hackers using that thinking.
Firewalls set to block those ports cause a different error to be returned than simply nothing, which sends a flag to any hacker wannabe that the computer is there.
Not running software on those ports cause the hacker wannabe to move along as it appears their is nothing to get to.
