- The Web site is hosted on Internet Information Services (IIS) 5.1 or IIS 6.
- The Web site has a name that is mapped to the local loopback address.
- When you configure Windows Small Business Server 2003, the SharePoint Web site is automatically configured to use only the NTLM authentication. Therefore, Kerberos authentication is not enabled.
- A static DNS record is created in the DNS database. The target host of the DNS record is the Fully Qualified Domain Name (FQDN) of the server.
- Windows Internet Explorer 8 introduces a security improvement that expands the use of Service Principal Name (SPN) from the Negotiate authentication to include the NTLM authentication. This security improvement helps protect against credential reuse and helps protect the system from loopback attacks.
