Proper settings to make WinXP machines do updates automatically.

Everytime I log on to a machine here at work it tells me there are tons of updates to do. This is because I am an admin on the domain and it is downloading the updates but not actually doing them. I know it is possible to set it up with AD so that updates are applied automatically (like at 2am Sunday night) but apparently I don't have it set right.

Can someone tell me what I need to configure on the domain or point me to an article which details how to get it setup?


I did a quick Google search: does this answer your question?
