I want to determine what ports are being blocked by an intermediate firewall
which I do not have control over, and which I'm not being told what ports are
and are not blocked.

What I'd like to do is run a program on a Windows server that will open all
unopened ports and then I'll run a scanner such as nmap to see what is and is
not being allowed through.

NetCat could probably be used in such a way, I was wondering if there is
something the already exists that can do this out of the box.
