We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
SYMPTOMS
When you run either the New Web Site Wizard or the New FTP Site Wizard, and accept the default IP Address and TCP Port values provided by the wizard, the following error occurs when you try to start the new Web site.
CAUSE
Because the wizard defaults to the IP Address and TCP Port values that are already in use by the default Web (or FTP) site, the new site attempts to use the same settings. IIS does not allow this, because each site must be uniquely identified by an IP Address, TCP Port number, or Host Header.
RESOLUTION
Specify a different IP Address, TCP Port number, or add a Host Header for the new site. To do this, perform the following steps:
- Start the Internet Service Manager (ISM), which loads the Internet Information Server snap-in for the Microsoft Management Console (MMC).
- Right-click the new service, and then click Properties on the Context menu.
- For a Web site, click the Web Site tab.
For an FTP site, click the FTP Site tab.
The default Web site uses TCP Port 80, and the default FTP site uses TCP Port 21.
