Hello All,

I have several W2K in local network connected to Internet.
At night I see some network and disk activity even when
nobody is using any of machines. The lights of network cards
and hard drives are blinking. Can anybody recommend
me some simple software tool to determine what application
is involved in this background activity?

Its probably just normal network activity - computers have a habit of
talking to each other:

"Are you there?"
"Yes"
"Are you still there?"
"Yes, I'm here, are you there?"
"Yes, I'm here..." and so on.

Hard drives may be blinking because the operating system needs to read
different components from disk just to maintain its "on" state.

However, if you need to check - I prefer freeware programs like TCPView from
Sysinternals - which I've just noticed, have been "acquired" by Microsoft.

That, and maybe windows update?

Network indicator showed the nonstop activity in both directions, I stopped another
computers and started TCPView. Then I closed all connections and stopped all
processes visible in the TCPView, exept "system". Only the listening connections
remained. But the taskbar icon was green all the time and the connection status
showed the increasing number of sent and received packets. I really don't know
is it normal or not and what can I do to check it more.

Get Ethereal (freeware www.ethereal.com ). It is a packet sniffer that will
allow you to examine your network traffic. If you are not sure how to use
it, google for ethereal tutorial.
