i am running ARCserve Backup V11 inc. Exchange Agent. when i modify a job, i receive an error message when i expand the Microsoft Exchange Server - Brick Level

Error message: "Invalid user ID or password submitted or Database Server instance many be inaccessible. If user ID is a Windows domain account, please use Domain\Username".

i then enter the Administrator username and password, try and expand the Microsoft Exchange Server - Brick Level option again, i receive the same error message.

i receive this log of a morning:

W3073
Unable to logon as user. (USER=Administrator, EC=Logon failure: unknown user name or bad password.)
