* environment variable, because environment variables are "software"
* related. However, a class like Win32_MotherboardDevice will not

* returns WBEM_E_PROVIDER_NOT_CAPABLE, this function is placed here as a

* WBEM_E_INVALID_PARAMETER if any of the instance properties

* Like PutInstance, DeleteInstance returns WBEM_E_PROVIDER_NOT_CAPABLE from

* definition and the declaration from DHCP_Server_Scalars.h
