uncheck a properties

hi gurus

I need to run this by you and see if you can help me.

I have an AD with various OU, within this OU I would like to check every user and see if the " password never expire" is checked , if it is , I need to uncheck it, is there a way to loop through the entire AD->OU and change only the ones that are check to uncheck.

Thanks a bunch gurus
