Port watcher

[unrealrocks]

Is there a program that I can use to watch what programs are using what ports on my PC?

[Stoo]

Yup..

if you open a command prompt and type "netstat -ao" you'll get a list of the ports and the owning process id..

if you want a program to do it in the windows environment, Active Ports works well

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint.
