You may wish to download the program ActivePorts. This will map what program has spawned the the process of interest, and also show you where on your hard drive the program resides.

If not, perhaps you could attempt to telnet or putty into the port, and see if it returns an error message which might give some more info. Another idea - try ethereal to capture the packet data and see what it contains. Also I believe nmap can attempt to establish what's listening on a certain port. It might give you more info than just system 4. Regards Colin ----- Original Message ----- From: "Buozis, Martynas" <martynas () ti com> Hello I need an advice. I have Windows 2003 server. It occasionally show strange and suspicious network behavior. I used command "netstat -abov" and Process explorer tool from Sysinternals to find process behind connections. I found that it is "System 4" and got stuck. How I can identify what is behind this "System 4"? I thought it may be hidden process, but RootkitReveal from Systinternals did not show anything. I will be grateful for any ideas how to identify what is behind these TCP connections from server to many computers! Thank you in advance.
