You can create multiple FTP sites using multiple IP addresses and multiple ports. While creating multiple sites with multiple IP addresses is a common and recommended practice, it can be more complicated because, by default, clients call port 21 when using the FTP protocol. Therefore, if you create multiple FTP sites using multiple ports, you need to inform users of the new port number so their FTP clients can locate and connect to the port.

If you create a new site using the same port as an existing site with the same IP address, the new site will not start. The general rule is that you can have multiple sites using the same IP and port, but only one site from this group can run at a time. If you try to start another site from this group, you receive an error message.

Important

You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
