Q156409: Basic Authentication Prompt Before NT Challenge/Response

Article: Q156409
Product(s): Internet Information Server

SYMPTOMS
========

If you select both Basic (Clear Text) and Windows NT Challenge/Response
authentication from WWW Services properties and try to access the web server
from a client logon to the Internet Information Server's domain, the web client
should use the client logon credentials from the cache. However, a Username
Password dialog box will appear on the web client.

CAUSE
=====

If you select both Basic (Clear Text) and Windows NT Challenge/Response
authentication from WWW Services properties, Internet Information Server should
try to authenticate with Windows NT Challenge/Response authentication first. If
that fails, Internet Information Server should try to authenticate with Basic
(Clear Text). However, it is a known problem that Internet Information Server
executes this sequence in reverse order.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Internet Information
Server version 1.0. This problem was corrected in Microsoft Internet Information
Server version 2.0.
