Cause

PowerProtect Data Manager 备份代理进行 Microsoft Windows API 调用，以确定主机是否属于群集设置的一部分。在 Windows Server 2019 上，当进行 API 调用时，它会生成上述错误消息。

Resolution

可以安全地忽略这些事件。这些错误不会影响 Windows Server 或 PowerProtect Data Manager 代理执行的备份。

PowerProtect Data Manager 工程团队与 Microsoft 合作寻求解决方案。预计在 v19.14 之后的 PowerProtect Data Manager 的未来版本中会提供修复。当有更多有关修复的信息可用时，本文将进行修订。
 
提醒：本支持文章仅涵盖备份 Windows Server 2019 或更高版本时导致的 EventID 为 81 的事件的发生。由于与 Microsoft Windows 群集关联的问题，可能会发生相同的 EventID。确定错误的原因并进行相应的处理。
