Help with download corruption problem

I am after some help please with an issue that apparently occurs
during downloading.
Binary type files (pdf, zip, exe etc) are often, not always,
downloaded but with corruption. On one test the same file, from same
server, resulted in 3 good copies and 6 bad copies. Many other tests
have similar results. Can also be sick in e-mail attachments. The
'errors' are often minor just a few extra bytes in a file.

The machine is a dual core AMD 4200 in an ASUS A8N-Sli Premium
motherboard. This has 2 LAN connections - I have the nvidia port
connected to the cable model and the other one to the inside LAN. The
nvidia hardware firewall is on usually - my records are not good
enough to prove it works with this off but there are never any
relevant messages in the logs

It is running XP SP2 with a shared internet connection. And here the
crunch - the downstream systems (inside the Lan) do NOT have the
problem. By my thinking every byte coming down the line to the
downstream systems will come in on the nvidia LAN, go through who
knows what software, and out the other LAN card. So it may well go via
the firewall software and anti-virus before leaving intact.

Any thoughts appreciated.

The early nforce5 reviews went into detail about the nforce4 data
corruption issues. Yes, they only talk about it after they have a
new product to sell you.

Turn off the nvidia firewall and active armor.

NVIDIA has dropped the ActiveArmor slogan for the nForce 500
release. The ActiveArmor firewall application has been jettisoned to
deep space as NVIDIA pointed out that the features provided by
ActiveArmor will be a part of the upcoming Microsoft Vista. No doubt
NVIDIA was also influenced to drop ActiveArmor due to the reported
data corruption issues with the nForce4 caused in part by overly
aggressive CPU utilization settings, and quite possibly in part due
to hardware "flaws" in the original nForce design.

We have not been able to replicate all of the reported data
corruption errors with nForce4, but many of our readers reported
errors with the nForce4 ActiveArmor even after the latest driver
release. With nForce5 that is no longer a concern. This stability
comes at a price though. If TCP/IP acceleration is enabled via the
new control panel, then third party firewall applications (including
Windows XP firewall) must be switched off in order to use the
feature. We noticed CPU utilization rates near 14% with the TCP/IP
offload engine enabled and rates above 30% without it.

Thanks, Sounds like this is the problem - bad news for me with a new
machine.
