Function Discovery Provider Host (fdPHost) Service Defaults in Windows 7

The FDPHOST service hosts the Function Discovery (FD) network discovery providers. These FD providers supply network discovery services for the Simple Services Discovery Protocol (SSDP) and Web Services - Discovery (WS-D) protocol. Stopping or disabling the FDPHOST service will disable network discovery for these protocols when using FD. When this service is unavailable, network services using FD and relying on these discovery protocols will be unable to find network devices or resources.

Default Behavior

Function Discovery Provider Host is a Win32 service. In Windows 7 it won't be started if the user doesn't start it.
