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.

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 number? "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. Regards, chchin
