We use NTBackup for a client running Windows SBS 2003 SE to run a daily backup scheduled to run every evening.
The backup is regularly failing to run but there is no consistent pattern.
When the backup fails there is no report logged for it within the NT Backup Logs, but if we look at scheduled tasks this shows that the task could not run. Looking at the scheduled task log this shows:
(ntbackup.exe) 10/09/2011 23:00:01 ** ERROR **
The attempt to log on to the account associated with the task failed, therefore, the task did not run.
The specific error is:
0x80070569: Logon failure: the user has not been granted the requested logon type at this computer.
Verify that the task's Run-as name and password are valid and try again.
The job runs with Domain Admin credentials and re-entering these into the job properties allows the job to run again for a few cycles but then fails again for the exact same reason.
I have looked at the following EE entry for this but this doesn't help unless I am missing where I can check the log on parts suggested in the solution. This problem happens irrespective of when the server was rebooted,
The event log does not have anything in it against the time that this job should begin.
I'd like to know if there is a known 'cure' for this.
