Windows 7: connection by the system process and killed process

08 Jul 2010   #1

Windows 7
connection by the system process and killed process

I have a few apps running, incl. Firefox, Outlook. I took down their PID and then exit those programs.

I run the following command:

netstat -a -o -b -p tcp

It will list many connections like below

TCP xx.xx.xx.xx:http ESTABLISHED 4184 [System]
TCP xx.xx.xx.xx:http ESTABLISHED 1245 [System]

The PID 4184 is the PID of Firefox. Yet it exited and no longer shows up in Task Manager. This remains true even after 30 min.

How long does Windows 7 keep the half-open the connection? I thought the timeout is 5 min.

The other group of PID never existed before and does not show up in TaskManager either. Since it shows System, I have no way to find out which process it belongs to. How can I find out?
