Broken assignment of FTP user isolation for the FTP server on the corresponding IIS Web Server.


  1. Assign the DOMAIN\pem_domain use for the FTP website:

    • Open IIS > Sites > PEM FTP Site for Shared Hosting.
    • Open FTP User isolation.
    • Set DOMAIN\pem_domain for FTP home directory configured in active directory.
  2. Restart the FTP service:

    net stop ftpsvc
