The Port Reporter tool logs TCP and UDP port activity. The tool is a small program that runs as a service on a computer that is running Windows Server 2003, Windows XP, or Windows 2000.

On Windows Server 2003 and on Windows XP-based computers, the service can log the following information:

?The ports that are used
?The processes that use the port
?Whether a process is a service
?The modules that a process loaded
?The user accounts that run a process
On Windows 2000-based computers, the service logs the ports that are used and when the ports are used.
