I am using ITaCS Change Password 2.5 webpart on wss3.0 for a while now and all of a sudden everytime a user trys to change their password they get the error.

>

User account can change passwords via ctrl+alt+del and webconfig is setup with identity impersonate="true". Any ideas why the webpart would stop working all of a sudden?
