Function Discovery Provider Host

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.
The following is a list of all aspects that are part of this managed entity:
For the Windows operating system to successfully detect and work with network devices, the Function Discovery Provider Host (FdpHost) service must be running. FdpHost must load two dynamic-link library (DLL) files, fdSSDP.dll and fdWSD.dll, as processes in its service. If these DLL files are not present, or if they are not correctly registered with the Windows operating system, the FdpHost service will not start.
