# Error Reporting

## IANet_ExtendedStatus

This section details how to handle errors generated by NCS2 WMI Provider.

How and when an error object is returned depends on whether a call is synchronous, semi-synchronous or asynchronous. In most cases, the HRESULT is set to WBEM_E_FAILED when an error occurs. At this point, however, it is unknown whether WMI or the NCS2 WMI Provider generated the error.

## Getting the Error Object

### For synchronous calls:

Use GetErrorInfo() to get the IErrorInfo object. Use QueryInterface() to get the IWbemClassObject that contains the error information.

### For asynchronous calls:

The IWbemClassObject is passed back as the last item in the last SetStatus() call.

After you get the error object instance, you can check the __Class property to determine the origin of the error. WMI creates an instance of __ExtendedStatus, and the NCS2 WMI Provider creates an instance of IANet_ExtendedStatus for errors relating to IANet_ classes and NCS2 WMI Provider.

IANet_ExtendedStatus is derived from __ExtendedStatus and contains the following attributes:

## Error Object Qualifiers

Context Qualifier | Description
Description | Description of the error tailored to the current locale
File | Code file where the error was generated
Line | Line number in the code file with the error
ParameterInfo | Class or attribute that was being utilized when the error occurred
Operation | Operation being attempted when the error occurred
ProviderName | Name of the Provider that caused the error
StatusCode | Code returned from the internal call that failed
ClientSetHandle | Client Set handle used for the operation
RuleFailureReasons | Reason for operation failure. An operation can fail because a technical rule has failed. (e.g., you must have a management adapter in certain teams).

## Error Codes

For all error codes, the NCS2 WMI Providers gives a description customized to the locale. Below is a list of possible error codes that the Provider may return. Error codes are in the form of HRESULT with severity set to one (1) and facility set to ITF. An application may use these codes as a basis for a recovery action.
