We want to force all users to change their password. I know i can go to each user in ADUC and select the option that the user must change the password. How can i do this for everyone instead of doing it individually? also can i make it so that they cannot use their old password again? I remember in NT4 they had these options under user manager for domains. In 2000 its all done with GPO's and AD but i am just not sure the best way to do it without screwing things up. thank you.
