  • I'm facing "500 internal server error" issue frequently with all my SharePoint sites. I have configured tracing on IIS and getting below as a warning. The application pool recycles issue immediately but it occurs again.

    HttpReason Internal Server Error
    HttpSubStatus 0
    ErrorCode 0

Provider type not defined. (Exception from HRESULT: 0x80090017).
