Upload problems with Windows XP SP2

[rhesus.monk]

I'm having trouble with uploads to web sites on my Windows XP SP2
machine. I basically can't upload any files in in a web request. If
I try going to a bandwidth test page, it does the download test fine,
but then won't even complete the upload test. I can't send emails
through my web email client. I can't upload files to web pages. Each
time I try it hangs and then times out.

It shouldn't be a browser problem. It is the same with Firefox and
IE.

I thought maybe it was a hardware problem. I tried switching out the
network cable, tried switching ports on my router, I even installed a
different network card with the same results on the new card. Clearly
it shouldn't be a hardware problem.

It isn't the internet connection. I have another computer going
through the same router to the same internet connection and it doesn't
have the problem. I can upload files over the network to the other
computer (though it does seem a little slower than download).

Firewall is turned off. I really don't know what else to look for.
Anyone have any ideas? I'm stumped.

Thanks,
Monk

Look in event viewer for specific details.Also,if switching cards & using
other
pcs thru same hardware,unplug modem/router,etc between components.

Thanks for the suggestion, Andrew. I've checked the event log and
absolutely nothing is written there when I have one of these upload
failures. When I switch the network cable and router port over I'm
powering off the router and the modem. It reconnects, gets another IP
address, and still the problem remains. Any other ideas? Anyone?

Anyone else have suggestions? Is there somewhere else I could go to
get more information?

Can you ping or tracert to any server? That sends data at least over
the internet. As much as its not http traffic, its traffic. ?
