Each Web site must have one home directory. If you are setting up both a Web site and an FTP site on the same computer, you must specify a different home directory for each service (WWW and FTP). The default home directory for the WWW service is C:\InetPub\Wwwroot. The default home directory for the FTP service is C:\InetPub\Ftproot. You can choose a different directory as your home directory. For more information, refer to About Web Site Directories.
To change the home directoryNote If you select a directory on a network share, you may need to enter a user name and password to access the resource. We recommend that you use the IUSR_computername account. If you use an account that has administration permissions on the server, clients can gain access to server operations. This seriously jeopardizes the security of your network.
