The AnonymousOnly property specifies whether the service or server restricts access to anonymous FTP users. If the value is set to true, only anonymous users will be allowed to log on to the FTP server. If set to false, users will be allowed to log on using a valid user name, as well as anonymously.
If the value of AnonymousOnly is set to true, and the value of the metabase property AllowAnonymous is set to false, no users will be permitted to log on to the FTP server.
