These methods return an HRESULT indicating whether they completed successfully. See the Error Values section for more details.

Error Values

[C++] These methods return S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

[Visual Basic] This property sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.

Remarks

Valid values for the Ncache property are between 0 and 9999. The default value is 30 days. If you increase the default, IP resolution will occur more quickly. However, domain name changes may not be caught.
