I have a problem with Windows Scheduler on a Windows Server 2003. NT Backup was set to run a backup every night. When I checked the backups I found that it only recently hadn't been starting.
I have checked the scheduler to see if it will open a Command console or Calc at a certain time. Scheduler will say the program is running but doesn't actually open it, the program is not shown in Task Manager.
All other system shceduled tasks run ok, ie Shadow Copy. The logs don't help as they report that the task started successfully. Rebooting and restarting the Task Scheduler service hasn't fixed it either.
