Iis 存在被动/端口问题的特定目录

很长一段时间以来，我一直有一个非常奇怪的问题让我感到厌烦，我没有找到任何线索来检查到底是怎么回事

我有一个ftp根目录，有很多目录，没有任何问题

在一个特定的目录中，我有一个包含多个目录的网站。在每个目录上，我在根目录上没有问题，但在子目录上，我只能在被动模式下下载，在端口模式下上载，所以我必须每次在模式之间切换才能工作

+ Site1 > no problem
  - directories > no problem
    - subfolders > no problem
+ Site2 > no problem
  - directories > no problem
    - subfolders > DL in PASV, UL in PORT

由于所有站点都在同一个IIS上，所有目录都具有相同的权限，我真的无法解释这个问题

如果有一天有人遇到同样的问题并找到了解决办法，我会非常高兴

谢谢：）

根据您的错误消息，这可能与防病毒干扰有关

如果您已在服务器中启用防病毒干扰，我建议您可以尝试禁用它，然后重试。

您可以发布FTP客户端的错误消息吗？@samwu edited，希望此帮助可以将您的问题移至（删除此处，重新发布）。是的。
