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
The following error message appears on a Microsoft Internet Explorer
client:
Error: Authentication is required for this document. The server did
not specify a supported authentication method."
CAUSE
A potential cause can be that you have set the Password Authentication on
the Microsoft Internet Information Server to a level that is not supported
on your Explorer client. The Windows NT Internet Explorer 1.5 Client will
only support Anonymous and Basic Authentication.
RESOLUTION
Currently, only Internet Explorer 2.0 for Windows 95 supports
Challenge/Response Authentication. Run INSTALL.BAT from the Internet
Information Server's \CLIENTS\WIN95 directory to install Internet Explorer
and the authentication module.
If Internet Explorer is not installed in the above manner, manually add the
authentication module by running IENTLM.EXE from the \CLIENTS\WIN95
directory.
