I came in to work today and a lot of users are complaining they are being asked to enter their username/password and are unable to access their email. I noticed that the Outlook automatically enters the Exchange server's computer name as the domain so this is the reason why they are not able to connect to the Exchange server.
I would like to check the reason why this is happening. Is there a way to check if the Exchange server and the DC is authenticated and communicating? AND how does Outlook users authenticate with the Exchange server...via Token? My Exchange server and DCs are Windows 2003 R2.
