How to trace netstat connection to kill process

Asked by: gmctech

In Windows, if I suspect I have been hacked, and that the hackers session is still current / active.  (ie.  I see that I have a large file being uploaded).

I understand from the netstat command I can see where I am connected to, but what I am really interested in is killing the connection.  

How do I identify which process to kill once I determine I am connected to something I dont want to be connected to?  
Please respond for both XP and Server 2003.

A utility like this: http://www.freshsoftware.com/xns/pro/

(X-Netstat) can be used to kill incoming/outgoing socket connections.

Thank you very much.  Your answers suited my immediate needs.  It is likely I will be purchasing the X-Netstat solution after the trial has expired.
 
However, your answers leave me a little disappointed.  I was hoping for a step-by-step walkthrough for how to manually trace / associate a network connection with a given o/s process.  

If anyone has that information readily available (how to . . . w/o using a tool), I would be most interested.

I can understand why you would want to know how things work to manually trace a network connection with a process but it all goes on at such a low level that there is no way of finding out that information without using a tool or programming one yourself.

If you would like to play around with a bit of programming, have a look at this site: http://msdn.microsoft.com/msdnmag/issues/04/10/NETProcessBrowser/

It's all about not re-inventing the wheel :)
