Your schemus task scheduler is not starting automatically, but can run manually via windows task scheduler.

The schemus config may have been migrated to another server while the old task scheduler still searching for the old scheduler file within the schemus installation folder.
Delete the old windows task scheduler and recreate a new one, and then point it to the Schemus scheduler file located by default under : C:\Program Files\Schemus (file : schemusc.exe )
Next step, is to ensure that the server has no pending Windows updates, If that is the case then a reboot will be required.
