anyone an idea? On my Win2k3 Servers all scheduled Ntbackupjobs are failing since a few weeks. It has been working. One peer has installed Arcronis some time ago. Since then we're facing this kind of trouble. If I RDP in to this machines I can copy the job into dos promot and Backup succeeds.
When checking Backuplogs, it is blank. In Applog just only 8019 NTBackup
maybe you'd changed the Password of the Account, the job's runnning in? Maybe this is the cause, why the job is running by copy it into CLI. I would try to set the Passwords in Scheduler again.
