Excessive Packets Problems

[Miller]

I have 2 computers and a combo ADSL modem/router. The
desktop computer is always connected and works with no
issues as long as the other computer, the laptop, is not
connected. When I connect the laptop, I can ping the IP
of the desktop from the laptop (and vice versa) but I
cannot ping the IP of the default gateway on either
computer. The laptop sends an enormous number of packets
to the router and gets little response. I cannot browse
the web with either computer when the laptop is
connected. Attempting to repair the laptop connection
does not helpOnce I disconnect the laptop, however,
everything returns to normal and I can once again ping
away on the gateway from the desktop.

I think the excessive packets are "drowning out" the
router and pretty much rendering it unable to respond to
either computer (which is why the desktop will not work
when it is connected). Is this feasible?

Also, this problem occurs whether I use the ethernet or
WLAN connection to connect the laptop to the router.
This leads me to believe that it is not a hardware
problem.

Thus, if it is software based, where should I look to
attempt to terminate this process...My task manager is
acting funny and disappears after I start it...is it all
just virus oriented?

Thanks,
Miller

On the laptop is the icon for the Internet Gateway showing in the
notification area (by the clock)? There was a bug where it would
continuously fetch statistics from the router if it was showing.

Most likely some sort of worm or virus, especially if it sends a flood of
network traffic and interferes with task manager.

If it is a variant of MyDoom, there may be a program running that keeps
growing until you cannot open any more programs (or task manager). When a
co-worker was infected with that, I started task manager immediately after
booting, found and killed an endlessly growing process, and Windows
Updates came up with a fix for it that it said would only show up if it
thought you were infected.

If by the IG icon you mean the icon of the 2 computers
that alternately flash on and off, then yes. The host
computer is showing that it is always sending traffic.

If it is a bug, how do I fix it?

Thanks for your expertise.

I'll try bringing up task manager immediately after
booting up next time I have the chance. Any suggestions
if I can't get it to function? Lately, I'll start it, see
it on screen for less than a second, and then it will
disappear, apparently minimized. I am thinking I might
need to completly wipe and reload the system if I can't
fix it. Any suggestions greatly appreciated to avoid this
scenario.

Just in case anyone is interested, I restored Windows to
its factory settings (this was surprisingly easy as I had
very little in the way of files to save) and now I have
no problems. I am confident now the problem was viral in
nature. Thanks for all the help.
