Media player problem

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.

Error ID = 0xC00D11B6, Condition ID = 0x00000000

I have watchguard firewall on site. Is there a port I have to open

    Which version of Media Player are you using?

    Youc ould try these article:  and clear the UDP to force it to use HTTP instead.

    You could also try upgrading to Media Player 10  if you haven't done so.

    It depends on the port the broadcaster is using.

    Microsoft specifys the following (;en-us;827562)

    Ports Description
    In: TCP on port 80, 554, and 1755

    The Windows Media server uses the TCP In ports to accept an incoming HTTP connection (port 80), an RTSP connection (port 554), or an MMS connection (port 1755) from Windows Media Player and other clients.

    In: UDP on port 1755 and 5005

    The Windows Media server uses UDP In port 1755 to receive resend requests from clients that are streaming by using MMSU and UDP In port 5005 to receive resend requests from clients that are streaming by using RTSPU.

    Out: UDP ports 1024 through 5000 and 5004

    The Windows Media server uses UDP Out ports 1024 through 5000 and 5004 to send data by means of MMSU and RTSPU to Windows Media Player and other clients.

    Now this is apprently for server side broadcasting, but you could try opening those ports ...

    Reading a bit, I came to understand that the statement I made: "It depends on the port the broadcaster is using." isn't entirely correct ...

    Just wanted to add that. It's a shame you cannot edit previous posts on these forums ...
