windows 2000 unwanted data transfer

A windows 2000 professional pc is used to access internet on a PPPOE
connection. The charges are based on the volume of data transfer. It is found
that large volume of data transfer take place even if the PC is left idle.
This was happening for Windows XP also, but stopped when service pack 2 was
installed. But even after installing service pack4 for win2000 the problem
remains. Antivirus check by Norton didnot find any virus.

Hi,

If I consider the differences that you describe in your post the answer
would be firewall. Windows XP SP2 will by default enable windows firewall.

Windows XP SP1 does come with firewall but it is not enabled by default.
Windows 2000 (even SP4) doesn't have in-built firewall. You will have to use
some 3rd party product like Sygate... It is free for non-commercial use...

You can download it from here...

As Mike said it was the fact that you have a firewall enabled by default in
XP SP2 that caused the activity to stop. I suggest that you scrap the pppoe
and get a NAT/router for your dsl connection. They are cheap and effective
for the average home type user. The link below shows one for example that is
less then $30 shipped. You can of course use a software firewall and Sygate
or Zone Alarm are good with Zone Alarm being easier to configure.

If Norton did not find the problem then first make sure your antivirus is up
to date with definitions, try a second opinion, and scan for parasites also
with something like AdAware SE which is free for personal use. I would also
scan your computer with Microsoft Baseline Security Analyzer to check for
vulnerabilities. You may find that with weak passwords, weak share
permissions, and unneeded services running such as WWW or FTP that your
computer is being used as a FTP server or such. The links below should be
helpful. --- Steve
