Windwos Vista WSDiscovery – FDPHOST.DLL
Fdphost.dll will be fuond in your Windows\System32 folder. It's part of the Windows Vista operating system. WS Discovery Service. Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. The WS-Discovery standard was developed by BEA Systems, Canon, Intel, Microsoft, and WebMethods. Various components in Microsoft's Windows Vista operating system, such as the "People Near Me" contact location system, use WS-Discovery. So unless this file is causing problems, we'd recommend leaving it in place.
