Windows 7 Pro Hang When Transferring Huge Files over Network RRS feed

  • Question

  • Hi,

    I have a problem with one of my client Laptop. Windows 7 Pro just hang whenever the user tried to transfer a huge file size over the network e.g. from server to laptop. He is using Dell E4310 with a single disk drive.

    Can anyone provide a solution to this?

  • Hi,

     

    This issue could be caused by the new TCP Auto Tuning feature include in Windows Vista and Windows 7 that uses a scaling factor communication between the server and client to negotiate a bigger window size during connection of the tow peers.

     

    To Turn off Auto-Tuning

    ==============

     

    1.press Ctrl+Shift+Enter to open the Command Prompt. Choose run as administrator.

     

    Type in: netsh int tcp set global autotuninglevel=disabled

     

    2.Reboot

     

    If you have any problems, then to turn auto-tuning back on type the following in Command Prompt:

     

    Type in: netsh int tcp set global autotuninglevel=normal

    Best Regards
