The Windows Media Station Service is a Media Player 9 server service that provides streaming media across the Internet. If you are runnning a streaming media server then this service should be left on automatic. My guess is that this service acts as a mechanism for differentiating several active streams so that a single server can provide multiple media streams. If you know the exact nature of this service then please contact me.

"He did not move. Eyes shut, he waited, shivering. He heard Travis breathe loud in the room; he heard Travis shift his rifle, click the safety catch, and raise the weapon. There was a sound of thunder." --A Sound of Thunder, Rad Bradbury
