IVdsServiceLoader::LoadService method (vds.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Launches VDS on the specified computer and returns a pointer to the service object.


HRESULT LoadService(
  [in]  LPWSTR      pwszMachineName,
  [out] IVdsService **ppService


[in] pwszMachineName

This parameter must be set to NULL.

Windows Server 2008 R2, Windows 7, Windows Server 2008, Windows Vista and Windows Server 2003:  This parameter contains the name of the host computer. Setting it to NULL causes VDS to be loaded and initialized on the local host.

[out] ppService

The address of an IVdsService interface pointer. Callers must release the interface when it is no longer needed by calling the IUnknown::Release method.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code Description
The service has launched successfully.


Although S_OK indicates that VDS has launched successfully, the service initialization can be incomplete when the method returns. For this reason, after calling this method, you must call the IVdsService::WaitForServiceReady method to wait for VDS initialization to complete.

For a code example, see Loading VDS.
