How do I know what process in Windos XP is using 1% of my bandwith when no browser, messenger or updater run?

I am a computer technician, with an antivirus running and working, spyware protected, all running good....but I need to know what application may I use to find out what specific task is consuming my bandwith, I suspected spyware or something similar, but know I am beggining not to trust Microsoft at all....

Microsoft has a port reporter that will tell you for free.





I use a firewall by eeye called blink. http://www.eeye.com. It tells me more than I want to know about what sockets are being used.





Blink also has an interesting way to detect attacks, at least buffer overruns. It does this detection by enforcing the rules of the protocols. So if a message that is ASN.1 encoded comes in and the message includes a text field whose length is supposed to be 10 characters, but the field is 20 characters long. Blink will discard the message assuming it is a buffer overrun attack. Blink will do this for messages where there is no known susceptibility, so that you aren't as dependent upon updates.
Reply:Even with no normal applications running, you will still be using network bandwidth just for the operating system to check the network connection, programs searching for updates including Windows updates and so forth. I would not be worried about that 1% at all.
