the code

  private string  CreateTask(int ID, string Time)
    {
        // Get the service on the local machine
        try
        {
            using (TaskService ts = new TaskService())
            {
                // Create a new task definition and assign properties
                TaskDefinition td = ts.NewTask();
                td.RegistrationInfo.Description = "Send Report By Email Schedule ID" + ID;
                td.Principal.LogonType = TaskLogonType.InteractiveToken;

                // Add a trigger that will fire the task at this time every other day
                DailyTrigger dt = (DailyTrigger)td.Triggers.Add(new DailyTrigger(1));
                dt.Repetition.Duration = TimeSpan.FromDays(5000);
                dt.Repetition.Interval = TimeSpan.FromDays(1);
                dt.StartBoundary = DateTime.Parse(Time);
                //  dt.EndBoundary = DateTime.Parse(Time).AddMinutes(20);
                // Add an action that will launch Notepad whenever the trigger fires
                td.Actions.Add(new ExecAction("C:\\Projects\\Report_Emails\\Report_Emails\\bin\\Debug\\Report_Emails.exe"));

                // Register the task in the root folder
                string taskName = "Send Report " + ID.ToString();
                //Error Here
                ts.RootFolder.RegisterTaskDefinition(taskName, td);
            }
            return "";
        }
        catch (Exception ex) { return ex.ToString(); }
    }

i think it is permission matter since it works local if it is a permission how to allow the remote user to create a task

thank you

Answer 1

As above this will run under the website user, what that is setup to be.

Given you need to grant specific rights I'd suggest having a dedicated user for task management. You can pass in this user when creating the TaskService , ie

using (TaskService ts = new TaskService(serverName, taskUser, taskDomain, taskPassword))
