    If you run the following command from a command prompt:

    netstat -a

    it will list all of the open connections to ip addresses and the ports they are operating on. This may help you troubleshoot the issue.

    However, is the default ftp site also running which may be interfering?

    Hello sparky,
    I have run netstat -a already, but its not listed, which I thought was odd, the default ftp site was (stopped) on port 21 if I create or swich to another port they work.

    Which FTP server are you using? Is it that there are two ftp servers running in parallel? You can use NMAP to check the port occupation.

    Hi, I'm using IIS6 on windows server. Nmap(zenmap) doesn't show anything other than port 80 which is my website port.
