海林檎（cystoids）是已灭绝的一类棘皮动物，是棘皮动物中最古老、骨骼组织最简单的一纲。形状为球形，与苹果类似，故名（林檎为苹果的古称）。牠們和海百合有驚人的相似處，都是利用莖節附著在基底上，有一個由許多不同骨板組成的膨脹殼。具有萼和腕，萼部骨板（萼板）多达13至200块，萼板上具有板孔，沟孔系统复杂。海林檎沒有真正的肢，因此牠們利用短小沒有分叉被稱為鰓的支臂從水中濾取食物。此外，牠們的骨板上有獨特的孔結構，用來呼吸。[1]海林檎纲约有100属左右，多生活在奥陶纪和志留纪，于泥盆纪晚期绝迹。

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
