The PostErrorLine method is received by the server in an RPC_REQUEST packet. In response, the server returns a textual representation of the data that follows the specific data in the administration system that is causing the error.

 [propget] HRESULT PostErrorLine(
   [out, retval] BSTR* pbstrPostErrorLine
 );

pbstrPostErrorLine: Contains the error data.

Return Values: The server MUST return zero if it successfully processes the message that is received from the client. In this case, *pbstrPostErrorLine MUST NOT be NULL. If processing fails, the server MUST return a nonzero HRESULT code as defined in [MS-ERREF]. The following table describes the error conditions that MUST be handled and the corresponding error codes. A server MAY return additional implementation-specific error codes.
