How do I use RunLevel and Configure For when creating a task?

[dumontjames]

Hello,

I am new to this forum and I apologize if this topic has been mentioned before.

I created some code in vb.net and I was successful in using the TaskScheduler library to create a task.
However, I get an error when using RunLevel to set the task to Run with the highest privileges. All event triggers that I create run batch files so this setting is necessary.
Is it also possible to set the "Configured for" to the version of Windows Server the program is run from?

Here is my code.

    Using tService As New TaskService()

        Dim tDefinition As TaskDefinition = tService.NewTask
        tDefinition.RegistrationInfo.Description = "Vault Basic Full Backup"

        tDefinition.Principal.RunLevel = TaskRunLevel.Highest

        Dim tTrigger As New WeeklyTrigger()
        tTrigger.StartBoundary = DateTime.Today.AddDays(2)
        tTrigger.DaysOfWeek = DaysOfTheWeek.Monday Or DaysOfTheWeek.Tuesday Or DaysOfTheWeek.Wednesday Or DaysOfTheWeek.Thursday Or DaysOfTheWeek.Friday
        tTrigger.WeeksInterval = 1
        tTrigger.Repetition.Duration = TimeSpan.FromHours(4)
        tTrigger.Repetition.Interval = TimeSpan.FromMinutes(10)

        tDefinition.Triggers.Add(tTrigger)

        tDefinition.Actions.Add(New ExecAction(VaultScriptFolder & "\VaultBackup.bat"))

        tService.RootFolder.RegisterTaskDefinition("Vault Basic Full Backup", tDefinition)

    End Using

Here's the error I receive:

An unhandled exception of type 'System.UnauthorizedAccessException' occurred in Microsoft.Win32.TaskScheduler.dll

Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

RunLevel
The default parameters for RegisterTaskDefinition have it run as the currently executing user, which could be one without privileges. See the documentation for the underlying COM object here to understand the security requirements associated with the property. You may be required to specify an account depending on your scenario.

Configured for
TaskDefinition.Settings.Compatibility is the property that represents the "Configure for" item in the UI. See the documentation for each of those enum values to understand how they translate to OS versions.

Hi David, Thank you for the information. Unfortunately, I'm not sure what to do at this point. My code is for my personal use but I intend to use it on many servers. I do not know the credentials that will be used to run the task. Currently, I have XML files that I import. Once imported, I have to adjust each task for certain settings. The IT manager is responsible to select to Run whether logged in or not and use appropriate credentials to run the task.
