Investigating which Windows service is listening to which IP and port

Asked 2008-11-03T08:33:34.820

I am investigating a production system where there are several Windows services communicating with each other through TCP/IP sockets. I'm trying to figure out which executable is listening to which IP address and which port on a given machine.

Other than rummaging through each windows service's obscure configuration files, is there a system tool that can more easily give me the details I want?

windows-services

Command line netstat tool might help you. To learn available parameters run it with /?: netstat /?

Or there is a better GUI alternative: SysInternals TcpView (freely downloadable from ms site)

Thanks everyone. Very helpful indeed. A friend also introduced me to a freeware utility called "Active Ports" from DeviceLock: http://www.devicelock.com/freeware.html/
