We currently have script in place that resets the password of a set of temp users we have set up. These users are reset each night and are then handed out again the next day on as needed basis. However, it has come to our attention that these profiles are getting huge on the various servers they have rights too. How can we remove the profiles from these servers each night from the same script if possible? What information do you guys need from me in order to assist me on this? Anything helps! Thanks!
