Vista's Function Discovery Provider Host Service

ServicesThe Function Discovery Provider Host service allows resources to be discovered over the network. One of the more notable resources that depend on this is the Media Center Extender (an XBOX that can play media from your computer), but it can also be used to discover networked cameras, printers, disks, etc. If you are fine with manually setting these items up you may be able to get away with disabling this service, but since the default setting is ‘manual’, you probably won’t save any resources, so you might as well leave it alone.

    Thank you for the great work. I searched the web and by far your descriptions and recommendations regarding Vista services are the most detailed.

    Function Discovery provides a uniform programmatic interface for enumerating system resources, such as hardware devices, whether they are local or connected through a network. Applications can use Function Discovery to discover which functions the computer can perform, regardless of the underlying device or software architecture.

    Function Discovery supports an extensible discovery provider model. The providers included in the system provide an abstraction layer over existing standards such as Plug and Play (PnP), Simple Service Discovery Protocol (SSDP), WS-Discovery, and the registry. Independent hardware vendors can also create custom providers to expose new device types through Function Discovery.
