I'm a math guy who's been trying to exploit mega- and now giga-powers. As my machines get older, they go on the network and get filled with less computational and more personal stuff, plus they go off support and get less of my attention. The problem I'm going to post is on an old Dell desktop running Win2K Advanced Server. I now use it to do my taxes once a year, and it's pretty much a doorstop otherwise. I'd like to maintain my collection of freebies on it (they always seem to go pro eventually...) and thus keep it active and protected (with the free security stuff...). Thanks in advance!
