Article: Q146815
Product(s): Internet Information Server
Version(s): 3.51
Operating System(s): 
Keyword(s): kbnetwork
Last Modified: 08-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Workstation version 3.51 
- Microsoft Windows NT Server version 3.51 
- Microsoft Internet Information Server 1.00 
-------------------------------------------------------------------------------

SYMPTOMS
========

When connecting to a Windows NT Internet Information Server (IIS), you receive
one of the following error messages:

  From Windows NT Internet Explorer 1.5:

  Authentication is required for this document. The server did not specify a
  supported authentication method.

  From Windows 95 Internet Explorer 2.0:

  Error: Access is Denied.

CAUSE
=====

Your Internet browser software does not support the Windows NT
Challenge/Response password authentication and this option is enabled on the
computer running IIS.

NOTE: This is not the default authentication method for IIS.

RESOLUTION
==========

There are 2 methods to resolve this issue:

1. Upgrade your client software to a version that supports Windows NT
  Challenge/Response password authentication. IIS ships with a version of
  Internet Explorer for Windows 95 that supports this method of authentication.

2. Change the password authentication on the IIS computer to either Allow
  Anonymous or Basic (clear text).
