    Is there a program for windows XP pro out there that I could use to trace the source program that is causing excess network traffic (seems to be datagram traffic as it is in most cases only outgoing without replies)?

    I have tried "task manager" and it gives me little indication of the offending program as the CPU usage is so low across all the programs using CPU.

    Not sure if this is related but my Norton Antivirus now seems not to be able to get definition updates and the subscription is still valid until 2004??

    I used a packet sniffer to identify the traffic and most of it seems to be going outside the local network to many different IP addresses.

    Is there a way of setting up or checking a log to identify the program?

    Cheers

    You might want to virus check your computer another way. Sounds like a virus to me. Could be some variant of blaster worm. The only one I'm familiar with doesn't block popular virus scans.

    If not, you can read up on Microsoft or any other major virus scan websites on how to fix the problem.

    Of course, I may be wrong and could just be some minor problem. But that's my two cents.

    I'm not sure I completely understand but are you concerned about a program accessing the internet? If so, how do you know this is happening? Do you have a firewall? If not, you could give the free basic version of Zone Alarm a try. It will alert you to programs when they try to access the internet and thus you'll have a better picture of what is going on.

    I have Norton Internet Security on the border PC that is using WIN XP ICS.

    The traffic seems to be constant upstream from the one pc. Thjis is evident from the network connection icon in the task bar. I also confirmed this by setting up a counter on ip traffic and viewing the results.

    Install a firewall on the offending PC, and block out outgoing traffic. When you get the pop-ups for access requests for the Internet from the system, you'll soon identify the offending application.
