NTAuthenticationProviders Metabase Property (IIS 6.0)
When Integrated Windows authentication is enabled, the NTAuthenticationProviders property contains a comma-delimited list of Windows authentication providers that you can attempt to use, including Integrated Windows authentication (also known as NTLM) and Kerberos.
Integrated Windows authentication is disabled by default if you install Windows Server 2003 Service Pack 1 (SP1) as part of a slipstream installation of a Windows Server 2003 operating system. If you install Windows Server 2003 SP1 by itself as an upgrade to a Windows Server 2003 operating system, the setting for Integrated Windows authentication is unchanged from its Windows Server 2003 setting. Integrated Windows authentication is enabled by default for Windows Server 2003 operating systems.
You can configure this property at the following locations in the IIS metabase.
