Port 1025 - opened by "System"

Just installed Win2k SP4 and closed all ports but one.

----------------------------------
c:\>netstat -an
Proto Local Address Foreign Address State
TCP 0.0.0.0:1025 0.0.0.0:0 Listening

c:\>fport
Pid Process Port Proto Path
8 System --> 1025 TCP

Process Explorer: shows "System Pid 8" as the parent of many child
processes such as SMSS, Winlogon and LSASS, so I'll assume it can't
be disabled.

WinTask Pro: Describes "System" as the Microsoft Windows System
Process, and shows no path to an executable.
---------------------------------

Does anyone know what 'System' does, why it's listening on TCP 1025
and most importantly, how to make it stop ?

sounds like svchosts.exe to me.
If youre in an NT based platform (xp for example) try this

C:\windows> netstat -ano
(to get the pid of the process or i see you use fport)

C:\windows> tasklist /svc -fi "pid eq XXX"
(where XXX is the pid)

Port 1025 shouldnt be running on your internet IP, it should just run on
0.0.0.0 for system use.
I remeber we had a big discussion about this when tracker claimed it was
redbroker trojan or some windows game.

I have two svchost processes with PID's 356 and 358.
My concern is with PID 8 "System", listening on 1025.

I don't think Port 1025 is running on my Internet IP, its on 0.0.0.0.

I'm not sure I follow... I thought when netstat reports "Local Address
0.0.0.0:1025" as "Listening" to "Foreign Address 0.0.0.0:0" it means
the local computer is ready to accept connection attempts to port 1025
on any adapter (ppp,ethernet,modem,etc.) from ANY remote host.

e.g.
c:\>netstat -an
Proto Local Address Foreign Address State
TCP 0.0.0.0:1025 0.0.0.0:0 Listening

Are you saying 0.0.0.0 is reserved for system use and no remote host
can connect to it?
