If you get one of the following errors while attempting to access MySBFiles - "Invalid Signature". "System error 2148072478" or "An extended error has occurred"; and you are using a computer running Windows 10 - then you need to map MySBFiles. 

Instructions:

  1. Open the start menu.
  2. In the search box type "PowerShell".
  3. Click on "Windows PowerShell".
  4. In the window that opens type (without quotes) "Set-SmbClientConfiguration -RequireSecuritySignature $true". Hit enter.
  5. Retry opening MySBFiles. If you can now access MySBFiles, then you are finished. Only continue to step 6 if you still cannot access MySBFiles.
  6. Go back to Windows PowerShell.
  7. Type (remove outer quotes) "Set-ItemProperty -Path"HKLM:\STSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force" . Hit enter. 
  8. Now you should be able to access MySBFiles.
