thanx guys/gurls...just fyi....i'm running windows 2000 Professional on 3 of my computers and windows 2000 Server on one of them. My uncle says that they are all connected to the server one. is it possible to network windows computers through a linux one??? cuz i don't really know anything about linux. oh yeah and all the computers are connected to the internet through roadrunner. What can i do to help secure my computers? should i find a more secure way of connecting them to my network? and if it is recomended to find another way, what should i do? thanx for the help, and keep up the good work!!!
