Calling a Host Integration Server Method through WMI

You have two options when calling methods through WMI: you may call a WMI method, or a provider method. A WMI method is supported by the WMI infrastructure, and provides general services such as query support or log on access. For example, Logging on to Host Integration Server Through a WMI Provider and Accessing a Host Integration Server Property through WMI describe calling the GetObject and ExecQuery WMI methods. In contrast, a provider method is supported by the provider, and is unique to each service. Most HIS provider methods deal with controlling services. For example, the WmiSna provider supports the MsSna_ServiceSNA class, which in turn supports the Start, Stop, Pause, and Resume methods. The actual process of calling a WMI method or a provider method is the same as calling any other COM or scripting interface.
