For NetBurner customers porting from the 2.x tools to 3.x: FTP_FAIL and FTP_OK were deprecated on Jan 16, 2008. These defines were removed and all server functions (denoted as FTPD) were modified to use FTPD_OK and FTPD_FAIL. This was necessary so that the FTP client and server header files could be used at the same time. If you have any errors in your application code, you can safely change all server functions from FTP_OK/FAIL to FTPD_OK/FAIL.
