Domain Users CANNOT logon to Exchange 2003 OWA - One Domain Admin can

I have a new installation of Exchange 2003 on a Server 2003 sp1 box. All users can access their accounts via Outlook 03' when on the network. However when they try to access OWA the logon attempt fails (HTTP/1.1 401 Unauthorized). I have one Domain admin account which is able to access it's mailbox via OWA. The following are the security logs from a failed attempt. Any help would be appreciated.
