XP workstation shows up in my Domain Listing

My Network Places - Entire Network - My Domain (Wrights)

Why does my workstation show-up as an available
server/shared PC. I have file and print sharing
deselected but my workstation still shows-up when I
browse my domain. Is there anyway to setup XP so that
it won't show-up? If you select an XP workstation at
this point, no resources are available because nothing is
shared but I would rather the workstation not show-up at
all, unless it is a shared resource.
Thank you!
