I have to manage a configured SQL-Server version 2005
and have setup Database Mail successfully - test mail works.
Also I've changed the agent service to a domain user with (currently) domain admin and db admin privileges.
Now I'm getting numerous login errors for this user
(error 18456 state 28000) [298] SQL-Server error:18456 error logging on user domain\sqlagent, [SQLSTATE 28000]
when running jobs with notification. Any idea how that can happen, when the agent service can be restarted without problem?
I've searched the web extensively but the only answers I can find are related to wrong passwords.
