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:

SUMMARY
When you administer your Web server with Internet Service Manager (HTML) through a proxy connection, you cannot use Windows NT Challenge/Response (NTLM) authentication.



MORE INFORMATION
Proxy servers will only allow your Web server to use Basic authentication.
