If you are getting a bunch of event error 529’s in your server event logs, it is most likely from FTP hackers trying to get in. You can eliminate this by using “net2ftp – a web based FTP client”.  It basically allows you to block port 21 at your firewall in front of your server and uses http for your ftp access through a browser. Notice I said firewall in front of your server. Do not turn off FTP on the server’s software based firewall as this will not work. You also must use the internal IP or leave as localhost.
