i run a windows 2000 sp4 and full security updates box and i turn off the default shares of C$ and D$. then i check a while later and they are turned back on! this is a huge security risk. why does 2000 insist on reseting these? i've noticed this type of behavior wtih things such as msn messenger where it resets the avatar. the box is adware, spyware, trojan, virus free. i have also tried it on many computers.
