0xC00D11B6: Cannot play the file
Windows Media Player cannot play the file. A network firewall may be
preventing the Player from opening the file by using the User Datagram
Protocol (UDP) transport protocol. To play this file, try opening the file
without specifying UDP.
When you enter a URL in the Open URL dialog box and the path begins with
"mmsu:" or "rtspu:", you are instructing the Player to open the file using
the UDP transport protocol. Try entering the path using a different transport
protocol (for example, "mms:" or "http:"
If you cannot use a different transport protocol to open the file, you may
need to turn off your firewall to play it. For information about turning off
Internet Connection Firewall, see Windows Help.
