We have Exchange 2000 that crashed recently. It came up fine, but now I have a few users that can't access their email. They get a pop up window to enter their password. They try it, but it gives them a login error. We use Active Directory so I reset the password. They can log into the pc and domain fine, but when they open Outlook, they get the pop up window. They can still access via the web, but not locally on the machine. Is there a setting on this machine that doesn't sync with the domain login/password? Any other ideas?
