We have an issue with changing Windows XP global password settings for all of our users. Many users have thin clients and authenticate to a Citrix server, where their login is managed, on the network. We want to change the password settings in XP, however, we do not have a way to have a message pop-up on the thin client user screens notifying them of a password change. How can we avoid 100s of help desk calls when we make the change in XP? Any suggestions of how to push out the change keeping password security in mind would be greatly appreciated. Thanks!
