I have a client with a strange issue. They have a Windows 2003 Domain with 2 Exchange 2003 Servers. They have it set for users to have to change their domain password after 30 days. Well when the users change their password they can log on to the domain. Then they launch Outlook and the get a pop up asking for a password. The new password won't work and must enter the old one. After some time it will pop up again and they need to enter the new one. What can I do to get the DC's to update with Exchange faster?
