The Network Load Balancing Provider communicates status and error information as follows:
- All WMI operations that produce an error create an __ExtendedStatus object. Depending on the source of the error, the StatusCode property of the __ExtendedStatus object may contain one of the values listed below.
- The MicrosoftNLB_Node methods also generate the following values which are returned through the ReturnValue property of IWbemClassObject.
