www.grc.com - Windows oriented, keep click on Shields Up!, "All Service Ports". Scans first 1024 ports, the privileged ports plus some unprivileged ports Windows commonly opens. You should recognize all open ports and know what program is listening on them.
Search Google for "port scan vulnerabilities" (without the quotes) for additional possibilites. Asking a friend to do a nmap or Nessus scan are also possibilities.
