The error message "The folder 'ftp://ftp.site.name/' is read-only because the proxy server is not set up to allow full access" appears when you use your Internet Explorer (IE) Web browser to connect to an FTP site. This error occurs when either you do not have write or delete permissions on the FTP server, or the browsing enhancements are not enabled in IE. You can fix this issue by disabling the Web-based FTP option on your browser. Note that you may need administrative rights to perform this task.
