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
When you try to view a secure web site from your Microsoft Internet
Explorer version 3.01 and earlier, you may get the following error message:
http/1.0 500 server error (-2146893048)
CAUSE
A problem exists with Windows NT Challenge/Response authentication of the
Web Proxy clients.
WORKAROUND
Use one of the following methods:
Methods One
- Make sure all clients are using Internet Explorer version 3.01
or later.
- Install Service Pack 2 for Microsoft Windows NT version 4.0 on
the proxy server.
- Install the Winsock Proxy client program on the client computers.
- In the Internet Explorer Proxy settings, type the name of the
proxy server for all protocols EXCEPT Secure. This will force
the browser to use the Winsock Proxy service instead of the
Web Proxy service when you try to connect to a SSL (secure) page.
All other browser requests will use the Web Proxy service and
still take advantage of caching. This method will allow the use
of Windows NT Challenge for all protocols because the Winsock
Proxy has its own Windows NT Challenge authentication built-in.
Method Two
Disable Windows NT Challenge/Response and enable Basic Authentication.
Method Three
Install the Winsock Proxy Client and disable the Proxy connection settings
on the Internet Explorer clients. All clients will use the Winsock Proxy
service only.
