I have two identical Asus motherboards: One running Windows XP, the other running Windows 7. When I run Wireshark on the WinXP machine I get approx' 1 error in 10,000 packets.

When I run Wireshark on the Win7 machine I get over 3,500 errors in 10,000 packets.

I've tried swapping the hard drives from one machine to the other but problem moves with the O/S. It seem to be the Win7 PC that creates a huge number of errors while the WinXP machine creates very few.

Any clues to this would be useful

Did you check your duplex setting on the Win7 box? To make sure that it matches whatever is set on your switch?

What kind of errors are you talking about? Checksum errors? It could be that the Win7 network driver does TCP checksum offloading while the XP driver doesn't.

Have a look at:

Oy! I should have thought of that. That's probably it!
