Hi folks, i found the solution for this problem, in Microsoft Page, under name Fix233567.
Apparently only happens to certain Pc or combined rare hardware.
In my pc, the transfer between WinXP pros Aprox 30 to 50mb/s with Vista 11mb/s and after few days 6mb/s.
Now with this fix 30 to 50mb/s :D
Info:
Copy process is very slow when you copy large files from one computer to another computer in a high-bandwidth network environment if both computers are running either Windows Vista or Windows Server 2008
