[ossec-list] equivalent of portsentry for windows? (ports scans detection)

[Blauch Armand]

Hello,
I'm looking for an equivalent of portsentry for windows machine (w2003
and w2008). I look for something first for scans ports detection and
then to log on a output file easy to read for ossec.
I'm trying some configurations tests with windows firewall, but it
doesn't work at this time.
May be somebody already know a solution?
