You can try Active Ports at http://www.protect-me.com/freeware.html which
tells you what service is using which port.  The best thing is, it's free.

Subject: Kerio Personal Firewall

Hello list,
           I am trying to configure Kerio Personal Firewall and this
allows me to specify explicitly which service is allowed inbound/outbound
connection thru either TCP/UDP including the exact port numbers and IP range
respond to.

My question is: Is there a software/utility that will tell me exactly which
service/application is currently listening on exactly which TCP/UDP port

"netstat -a" only lists the active listening ports but doesnt tell me which
service/application is listening on that port for incoming packets.

I would like to "lock down" the server as much as possible by specifying
exactly which port and service a connection is allowed. Thanks in advance.
