Windows Media Device Monitor - WMPNSCFG.EXE
Microsoft Windows uses wmpnscfg.exe to alert users when media rendering devices are found on the network. Wmpnscfg starts the Windows Media Player Network Sharing Service (NSS) and then waits for notifications from the service. When wmpnscfg is notified that a new media device is available on the network, it displays a popup in the system tray that informs the user about the availability of the new device. If the user clicks the popup, wmpnscfg launches Windows Media Player, which displays a dialog box that asks the user to either allow or deny sharing with the new device. You'll find more information on sharing your media using the Network Sharing Service at http://www.microsoft.com/windows/windowsmedia/player/faq/sharing.mspx.
