David is quite right, and use of and interpretation from a network
sniff is simple once one has done it a number of times, but at first . . .
I would still like to hear what results you have when
a) trying from a different machine with any browser, IE or . . .
b) trying from the machine where this fail but using a different browser
Very much could be determined from that information.

This sounds great, David! The closest to a solution I have ever been!
But I have no idea what a network sniff is or how to take one? I'm not
that
advanced. Can you tell me how to do that and I'll be glad to post the
results.
Thanks so much!

The error you are getting back is 401.2 (IIS Custom Error) which
indicates
that the "client" insists on using an authentication protocol that the
server is not configured to accept. A "client" may be your browser, or it
may be any proxy servers between your browser at the target server - this
partly depends on your browser configuration.
This issue is straight forward to diagnose. Reseting IE settings, using
other browsers, or making any other configuration changes are not
necessary.
Why? The issue boils down to:
1. The server is expecting the "client" to send something
2. But the request received from the "client" does NOT contain that
something
3. This automatically results in the server sending back the 401.2 error
that you see.
All you have to do is:
1. Take a network sniff of the traffic from when you make that first
request
to the website admin console until when you get the 401.2 error page back
2. Post the request and response headers from the sniff
The network sniff will clearly show:
1. What authentication protocol(s) the server expects via
WWW-Authenticate:
2. What authentication protocol the browser chose via Authorize:
With this information, you know where the mismatch comes from and the
exact
configuration change that is necessary to remove the mismatch.
Of course, I am assuming that your website admin console is not using
custom
authentication protocol, or that there aren't custom binaries modifying
request/response outside the client-side, but even if it is the case, the
diagnosis steps will be similar.

Basically, until you provide this information, we are all guessing,
pattern-matching, and working around your missing information.

I reset everything to default in IE that I could find and it still did
not
work. Could it have anything at all to do with the fact that I'm on a
dialup
connection?
Thanks for your help.

I would agree with Roger, if the service providers server isn't
allowing
you
to connect in IE with default settings, the most common configuration
out
there, then this is likely a server side issue.
Thanks,

I'd be eternally grateful.
When I try to log in to my website's administration console to view
the
visitors stats for my pages, I get the following message:
You do not have permission to view this directory or page using the
credentials that you supplied because your Web browser is sending a
WWW-Authenticate header field that the Web server is not configured
to
accept.
I have reset my IE 6.0 back to default settings, but this still does
not
work. Can anyone help, please?
Thanks!
