The MessageBox will block your UI thread while displayed and you will not reach the timer.Stop() before you click the dialog away. Try stopping the timer before you display your MessageBox:

private void timer2_Tick(object sender, EventArgs e)
{
    DateTime Date = DateTimePickerReminderDate.Value;
    DateTime Time = DateTimePickerReminderTime.Value;
    if (DateTime.Now.CompareTo(Date) > 0 && DateTime.Now.CompareTo(Time) > 0) 
    {
        timer2.Stop();     

        Date = DateTime.MaxValue;
        Time = DateTime.MaxValue; 
        MessageBox.Show("Your Reminder");
    }
}
