Application for Motherbox:

SMB sharing under Windows Vista and Windows 7

Here is how you configure Windows for accessing network sharing for the Motherbox


The Motherbox supports access to the internal 750MB (approx.) memory via SMB sharing (SMB = protocol name), Server Message Block). This function can be turned on or off in the device configuration under Home >> Configuration >> Motherbox >> Network using the option Activate SMB server. Signing is then possible over using the Windows network environment.

It is not possible to log in to the SMB share under Windows Vista and Windows 7, including their server variants, using the standard operating system settings. These operating systems expect the authentication method NTLMv2, which is not currently supported by the Motherbox. After entering and confirming the euser name and password, the login dialog always appears after attempting to log in. The solution to this problem can be found in the Control Panel under Administration...

  • Open the Start menu and select Control Panel.

    1
  • First select System and Security, then Administrative Tools,...

    2
  • ...then Local security policy,...

    3
  • ...then Local policies,...

    4
  • ...then Security options.

    5
  • Double-click on Network security: LAN Manager authentication level and set the value to Send LM and NTLM responses.

    Confirm by clicking on OK.

    6
  • Double-click on Network security: Minimum session security for NTLM-SSP based clients (including secure RPC clients) and uncheck the value Require 128-bit encryption.

    Confirm by clicking on OK and close all open windows from the configuration process.

    You can now reach the SMB share of the Motherbox over the Windows network environment.
