To tell you the truth...Windoze2000 has alot of security lock-downs. I think it will be a good idea not to install anything that you are not supposed to because then you are going to make it hard for other people to be trusted, especially at this moment with the world-occurences. I am not trying to tell you what and what not to do...I am just trying to give you some helpful advice. And yes it does has something to do with the registry. If you ever notice...whenever you install a program that updates your system config...your registry updates as well. One thing admins do to protect the networks is to make sure that no one can get into the registry because anyone with knowledge of gaining root access knows that once you gain registry access...YOU GOT ROOT!!!...Temptation is a mother f#cker...just be careful...the choice is yours...peace.
