In my factory, we have two non-networked windows xp machines connected to some industrial equipment. Every day, they log the information that the equipment passes on. I've been backing them manually every month, because I can't get the task scheduler to work.
The machines are running as administrator, without passwords. When I schedule the task, usually between 12-3 AM, it simply won't start. I get a message "Task failed to start" and an error code 0x0.
I tried going to the local policy editor, and specifically added the local administrator account to the "backup files and directories" policy, but still no dice. I googled the issue, and all anyone said was try unchecking the "interact with desktop" box in the task scheduler service, but it's already unchecked. These machines were never part of a domain, so I don't think it could be a group policy issue.
Anyone ever encounter something like this?
