can't connect to audio stream

My computer suddenly does not connect to an audio stream like it used to. Something must have changed and I can't figure out what. I'm using Win2k and windowsmedia player 9. The player launches but will not connect. I've tried to reinstall the media player and IE6 ...no change. I also disconnected my anti virus software and disabled "spybot"....still nothing. Any suggestions would be appreciated.
Thanks
Gene
