When trying to access a machines Scheduler under Manage > Scheduled Tasks the following error occurs:
[Window Title]
Refresh Machine
[Main Instruction]
The scheduler on machine 'MACHINE-NAME' is not available. (Error: -2080374779)
The list of jobs currently scheduled on the remote machine is unreadable.
[Content]
Upgrading the scheduler will allow you to view scheduled jobs.
An associated error from the ST.TaskScheduler.Managed log file is:
at ST.TaskScheduler.ThreadedSchedulerJob.GetJobs(ManagedMachineDetails managedMachine)
at ST.TaskScheduler.ThreadedSchedulerJob.GetJobs(ManagedMachineDetails managedMachine, Boolean& schedulerAvailable)
| Cause |
|---|
This issue is caused by the Scheduler of the Protect Console being a newer version than the Scheduler files on the target machine. This often occurs when an upgrade of the console has occured.
| Solution |
|---|
Choose to 'Upgrade scheduler now' to upgrade the necessary files on the target machine and re-establish a connection to the target machines scheduler and scheduled tasks.
After selecting to Upgrade the Scheduler, assign credentials with local admin rights to the target machine to perform the action.
| Alternative Solution |
|---|
In some situations the automated upgrade may fail. An associated error from the ST.TaskScheduler.Managed log file is:

In this situation a manual uninstall/re-install of the scheduler on the target will be necessary.
