The reason I'm concerned is that in order to install some security patches I need sp4. I had Nachi and McAfee said it got rid of it, but problems remain. Every time I start my machine my hard drives are set on shared, and who knows what else I haven't explicity noticed yet. I obviously don't want this. Anyone know how I can get sp4 on my machine and get rid of whatever is setting my hard drives to be shared (either separately or together)? Thanks.
