I cannot listen to radio streamed sites on the internet. Sometimes I get a message of "mysqladmin flush-hosts" and other times just no sound. Any advice?

The flush host thing looks like it's more likely a problem with the station you are trying to access, not your PC.

As for the no sound problem, can you give us some more information:

• What program are you using to listen to the streamign stations?
• Have you tried any other programs and got the same problem?
• What's your version of Windows?
• Have you tried many different stations?
