I have this one Mac user who keeps getting locked out of his account on our Windows 2003, Active Directory server based domain. This happens roughly two to three times a week. The user interfaces with Windows resources via Entourage, miscellaneous Windos based servers and perhaps somehow via Keychain. I have had the user delete his entire keychain database and all prefs but the problem still occurs. He is not typing the password incorrectly. The problem MAY have started when we last attempted to change his Windows domain password... Thanks.
