i have spoken to my ISP and they assured me the port forwarding is still correct. if i use the ftp site internally it works perfectly but access from outside gives these errors.
i have double check ports on firewall is open.
i have recreated the ftp site, did not work.
i have restarted the server, did not work.
i have installed all the newest updates from windows updates after the problem occured this did not resolve the problem.
useing telnet im able to get to the username/password authentication after that it just goes out of the ftp.
Kind Regards
