Identifying a task connected to a port

[A. B. Nelson]

I have a Windows 2000 pro workstation that is sending a
broadcast every couple of seconds to UDP port 41. How do I
identify the task that is sending these broadcasts?

There's an MS tool that will give you this information, but the name of it
is currently escaping me. I use FPORT, a free download from Foundstone,
that will give you a list of all ports in use on a machine, and which
executable is using said port:

Use a third part tool such as fport or TCPView. They should be able to map the port
to the executeable. Process Explorer can also show what ports a process uses but you
will need to look at the properties of each process. --- Steve
