SYMPTOMS
In Microsoft Windows Media Player 10, when you set the Automatically Detect Proxy Settings option for the MMS (Microsoft Media Server) or RTSP (Real Time Streaming Protocol) protocol, the proxy autoconfiguration does not correctly work.



CAUSE
This problem occurs because Windows Media Player 10 uses certain functions within WinHTTP when it tries to download the Web Proxy Automatic Discovery (WPAD) or proxy auto-configuration (PAC) file. Windows Media Player 10 receives an error because WinHTTP does not correctly recognize the MMS or RTSP URL schemes.
