Hi phenix -
Rest assured Windows is doing what you told it.

The IP shown for FreeStaffWorld is "localhost", that is, your computer. The good news is all that happened was WMP wasted a bit of your computer time.
I only have W2K, didn't know WMP has a network sharing service -- it must be in WMP10+. Anyway, what siria said is good: at the very least set it to "Manual", but disabling it can't hurt. If disabling it does give problems, you can always reset to manual.
Cheers,
Gordon.
