SYMPTOMS
When you set up Internet Explorer 3.01 for Windows 95 or Windows NT or
Internet Explorer 3.0 for Windows 3.1 using Microsoft Internet Explorer
Administration Kit version 3.2a, an Auto Configuration URL can be specified
so that the settings for Internet Explorer can be changed each time
Internet Explorer is started. At startup, Internet Explorer will read a
.ins file from a specified server and update any changes in the .ins file.
However, if the .ins file is located on a Web server using only Basic or
Windows NT Challenge/Response authentication, the .ins file is not read and
the settings are not applied.
CAUSE
When Internet Explorer is configured to use an Auto Configuration URL to
read a .ins file, it first tries to anonymously access the Web server. If
anonymous access fails, other authentication mechanisms are not tried.
WORKAROUND
Enable Anonymous authentication on the Internet Information Server or move
the .ins file to a Web server that can use Anonymous authentication.
STATUS
Microsoft has confirmed this to be a problem in Internet Explorer
Administration Kit version 3.2a. We are researching this problem and will
post new information here in the Microsoft Knowledge Base as it becomes
available.
