  • 沙洛維龍科 Sharovipterygidae


  • 長頸龍科 Tanystrophidae



原蜥形目（Prolacertiformes）又名原龍類（Protorosauria），屬於雙孔亞綱的主龍形下綱，生存在二疊紀與三疊紀。許多物種已演化成樹棲生活，包括有三角形翼的滑翔動物沙洛維龍；其他如長頸龍，擁有長而疆直的頸部，可能用來捕抓魚類，可能是部分水生動物。


其他瞭解不多的爬行動物，有時會被研究人員歸類到原蜥形目，包括：鐮龍科（Drepanosauridae）[1]、長鱗龍[2]、翼龍目[2]。在2004年，菲力·森特（Phil Senter）將奇特的樹棲動物－鐮龍科、長鱗龍，重新歸類到鳥首龍目（Avicephala）[3]，此目為更原始的雙孔動物，但有些研究人員仍將這些動物歸類於原蜥形目。

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...
