I am running Windows 7 x64 with an AMD Phenom II 3.3Ghz 6 core.
Everything on this machine works wonderful and blisteringly fast, except copying large files.
When trying to copy a large file 1GB (Access MDB file) to a networked drive, it says that I should wait 19 HOURS.
It never finishes and eventually bombs out. Even if I click Cancel, it refuses to cancel. The only way to get the copying to stop is to do a shutdown and reboot. I have tried using xcopy /J from a CMD prompt, but that also does not work. It has been running now for about one hour and not a response.
Strangely, when I copy this file FROM the mapped drive TO my PC it copies in seconds. But it refuses to copy back to the network drive at the same speed. So far I had to keep using my flash drive and manually copy the file back to the networked PC each time.
I have tried:
netsh int tcp set global autotuninglevel=disabled (from eleveated CMD prompt) - No luck.
xcopy /J - No luck
Found this link and now going to try that:

If you have any other suggestions, please let me know, thanks!
