The following article will assist you in configuring FTP user isolation in the IIS web server.
1. In IIS Manager, Expand the Sites tree and select the website of interest.
2. On the Features view, you will see icons for all of the FTP features. Double-click the FTP User Isolation icon.
3. You will find different 5 options there:
Do not isolate users. Start users in:
FTP root directory
If you enable this option, all FTP sessions will start in the root directory for the FTP site.
User name directory
If you enable this option, all FTP sessions will start in the physical or virtual directory with the same name of the currently logged on user if such folder exists. In case there is no such folder, the FTP session will start in the root directory for the FTP site.
Isolate users. Restrict users to the following directory:
User name directory (disable global virtual directories)
This option will isolate FTP user sessions to the physical or virtual directory with the same name as the FTP user account. The user is allowed to see only their FTP root location. Therefore, they are restricted from navigating higher up the physical or virtual directory tree. Any global virtual directories created will be ignored.
User name physical directory (enable global virtual directories)
This option specifies that you want to isolate FTP user sessions to the physical directory with the same name as the FTP user account. The users are restricted to their own FTP root directory only and cannot navigate higher up the physical directory tree. Any global virtual directories created will apply to all users.
FTP home directory configured in Active Directory
This option will isolate FTP user sessions to the home directory configured in the Active Directory account settings for each FTP user.
