A few times over the last few months, users have complained about extremely long password change wait times. I can't find anything about this anywhere. Is there a common cause for something like this? We're using Windows 7 and Windows XP on a Windows 2003 domain.
Addenda: I have only one site with two domain controllers. I'm not aware of any replication issues. dcdiag /test:replications passed with flying colors and repadmin /showrepl shows successful replications. If you have any other specific tests you'd like me to try, let me know.
repadmin /syncall & repadmin /showrepl show no errors and execute almost instantly.
