  • Question

  • All other applications run fine between server and workstations. Have tried the following:

    Open command prompt and type:

    netsh interface tcp set global rss=disabled

    netsh interface tcp set global autotuning=disabled

    Restart server


    1.Run "regedit" on Windows Server 2008 based computer.

    2.Expand and locate the sub tree as follows.


    3.Add a new REG_DWORD key with the name of "Smb2" (without quotation mark)

    Value name: Smb2

    Value type: REG_DWORD

    0 = disabled

    1 = enabled

    4.Set the value to 0 to disable SMB 2.0, or set it to 1 to re-enable SMB 2.0.

    5.Reboot the server.


    Modify a serial registry key to control Windows Size and related network parameter.
