Microsoft Exchange Server has detected that Basic Authentication is being attempted between this server and server 'EXCHSRV'. This authentication mechanism is not secure and it is not supported between front-ends and back-ends. If this condition persists, please verify that server 'EXCHSRV' is properly configured to use Integrated Windows Authentication for each virtual directory used by Exchange. After applying any changes it may be necessary to restart Internet Information Services on both the front-end and back-end servers.
