Function Discovery Provider Host

Default Description:

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.

Additional Information:

Windows Media Center uses this service to discover and connect to extenders and the new "HomeGroup" connectivity requires this service.
