I have a Windows 2000 AD domain that has been working well for over 4 years. My motto is, if it’s not broke, don’t fix it. With being said, I have not made any global or local security changes in quite some time. About a week ago, a message started appearing when users try to change their password telling them that they are not authorized to change it. If they do it from the server, it allows the change. If they try from the client, it won’t allow it and gives them the autorization message. What could be causing this issue?
