I have a bit of a problem.

In the last couple of days, my Network connection runs all the time
downloading something or checking something, I'm not sure which but it
seem to have a ton of packets sent and received. But nothing is going
on, most of the time the computer is setting idle - but this activity
just goes on and on. I am running WinXP with all updates, I have a
Local Area Network to also link my laptop to the network via a Linksys
4-Port Router which I have used for quite some time. As I said, this
activity just started in the last couple of days and I cannot figure
out what is causing it or how to fix it.


You don't mention what problem you're having.


The problem is, this constant activity is causing my computer to slow
down and freeze at time - did not happen until a couple of days ago.
No new hardware installed.

If you're just curious
about the traffic, there are some things you can do. Off the top of my
head, and in no particular order:

a)go to Computer Management and expand the Shared Folders branch. Look
at Sessions and Open Files to see if any clues jump out.


Sessions had no items - Open Files had no items.


b)from a Command Prompt, run "netstat -a" to see what connections are
open.


I did that and have a copy of the results, but do not know what to
really look at in the results - can you advise as to what to look at
or for?


c)in Task Manager, select the Networking tab and look at the Network
Utilization to see how much traffic is involved.


It appears to be at 1% or less most of the time.


d)pull the WAN cable from the router to see if the traffic stops. If
it stops, it was LAN-WAN traffic. If it doesn't stop, it's LAN-LAN
(intraLAN) traffic. Not a definitive test, but helps determine where
the endpoints may be.


Looked at the box, but am not sure what the WAN cable is - have 3
cables in it (not including the power cable), one to the computer, one
to the Internet, and one that I can plug my laptop into.


e)use a packet capture program such as Wireshark to view the actual
traffic. This will allow you to see the source and destination IP's
and ports, the traffic type, and the actual payload. Expect to be
overwhelmed if you haven't been here before.


Not sure what Wireshark is - are you referring to the Wireshark
Capture Filters program I saw on the Internet or something else?


f)'other' - for everything not mentioned above, including malware
scans with something other than Norton.


I have Spy Sweeper and SpyBot installed, but run them in manual mode
instead of live as to not conflict with NortonAntivirus. Will run a
scan with them in a few minutes.


Any thoughts on what might be causing this problem?


I'm still not sure what problem you're having. Every LAN has (nearly)
constant activity.


The problem is, this activity slows my computer and freezes it at time
- tons of "packets Sent and Received" and constantly increasing.
