After researching this problem for a day, I have come to the conclusion that there’s no one-and-for-all solution. Some people have luck with a certain setting while some other users do not gain anything from that same setting. However a hotfix works for both of my computers – a Pentium Celeron desktop and a Dell Core Duo laptop. The hotfix is available here.

I have tried every possible configuration including the new “request only” patch from MS.
What did work for me was tweaking my NIC settings.
I have an onboard Marvel Yukon Gig-E and i changed these settings:
Energy Star – Disabled
Jumbo Packet – 4088
Max IRQ per Sec – 10000
Priority & VLAN – Disabled
Receive Buffers – 512
Transmit Buffers – 512
This netted me a change in copy speeds from 2mb\s to 11mb\s. Still not fantastic, but better than nothing.
