Right now I am at school and I share my printer on the network with my roommate so he wouldnt have to buy his own printer, recently ive noticed random ass people have printed stuff to our printer, so after some investigation i figured out this secret file...

C:\Documents and Settings\Jimmy\NetHood

so i go there and i see like 5 other peoples computers in that folder that i had access to and like all there shared documents and stuff.. weird huh? Also I saw my computer networks name in that file so i clicked my computers name and there was my printer and shared pics and shared music.. so for now ive deleted all the stuff in my shared folder and put a file in there that if anyone clicks they will learn their lesson the hardway, but how do I get my computers name out of the Nethood? Its still there and the printer is still there too =(
