Gary,

Let's see...FoundStone's fscan, SamSpade, etc, can all
be configured to do this.  Since all you're seeing are
the SYN packets, this could even be done using nmap on
NT/2K.  Or a Perl script.

Greetings,

Can anyone tell me which Windows tool is used to
scan for ports 139, 12345,
and 27374.  (Example below) This occurs often enough
that it makes me think
that it's a tool, I just can't find any mention of
it anywhere...
