Lose IE and Outlook Express after 10 minutes

[cawley]

After a fresh reboot I can access websites and my mail
server using outlook express, everything works fine.
However, after about 10 minutes websites start to load
slower, pictures don't load, and I can no longer access my
mail server. A reboot solves this problem. I have
cleared my internet temp files, reset all of my web
settings to default, used the handy repair tool in my
network settings. All to no avail. No other computer on
my network has this problem.

The strange thing is that when my connection goes sour I
still get an IP from my DHCP server, can still ping out to
websites, and can still Remote Desktop in through my
firewall. I also believe that if I use a download manager
while the connection is sour I still get great bandwidth.
The download could have a delayed start though. I am not
100% sure of that. I have not added any new software nor
have any settings changed besides resetting the web
settings to the best of my knowledge. Anybody have any
idea what is going on?

I have a very similar problem. It only happens when using IE6, not when
I use Mozilla or Firefox. It doesn't happene to me after a certain amount
of time, though. I haven't been able to find a pattern.

I'll be browsing on any number of sites and will have no problems when,
out of nowhere, I get a 404 error. I then try to access any web site and
get the 404 error for all of them. I can get my e-mail from POP3 servers
but, when I try to get my e-mail from Hotmail (downloads to my outlook
mail file), I get an error.

So, basically, I lose HTTP connectivity. That's it. I can do everything
else. I've run ad-aware, spybot search and destroy, and hijack-this but I
haven't been able to find the cause.

Any ideas?

Thanks.
