Ive tried streaming a number of videos today over my uni network but none work. i get this error in WMP:

"0xC00D11BB: Cannot play the file
Windows Media Player cannot play the file because the specified protocol is either not supported by the Player or not supported by the server.

If you encountered this error by clicking a link on a Web page, the link may not be valid.

If you encountered this error by typing a Uniform Resource Locator (URL) in the Open URL dialog box, try opening the file by using a different transport protocol (for example, "http:" or "rtsp:").

A list of protocols supported by the Player and the correct syntax follows:

mms://server/filename (for example, a file with a .wma, .wmv, .asf, or .mp3 extension)
http://server/filename
rtsp://server/filename
mms://server/sami.asf?SAMI=http://server/sami/sami_demo.smi (SAMI file)
If Windows Media Player supports the protocol and you still cannot play the content, ensure that the Player is configured to use all of its supported protocols."

Does this mean that it has been blocked via firewall or could it be that network traffic has slowed the system up??
