net, oh yeah, code red......if they didn't fix themselves the first round,
what makes you think they will fix it the second time, or the third...

the reason is that ms sql and msde are vulnerable out of the box, and 
since ms is such a popular o/s, you can be reasonably certain that new

another vulnerable box on a big pipe?
