Weird network activity

[dtc]

Hi...

My computer at the office is powered on 24/7. Staffs have no right to alter the setting of the anti-virus software of the computer. The system was OK last Friday. Yesterday, my computer prompted for "chkdsk" and then kept on rebooting. Then, when I got the chance to enter the Windows (XP Pro SP3) and the system became stable, I note that the network icon at the system tray continuously shows some network activity (see image below) even though I do not surfing. Kindly comment.

netstat -no

check for PIDs with a lot of network connections, match that to the PID in task manager (view -> select columns -> Process ID)

Thanks I will give a trial...

"netstat -no" shows PID with "0".

From Windows Task Manager, the process with "0" PID is "System Idle Process" and its "CPU" usage is "99". Do you think it's normal?

I've got a few of those too (XP SP3) so I'd say yeah it's normal (mine are all time_wait connections to port destination:port80).

the netstat -no shows you all your current network activity - which should equate to flashy lights on the taskbar. Then it's just a case of matching up PID's and finding out which are expected.

Mine are all "Time_Wait" connections too...
