Hi, I just installed IIS 5.1 and it works wel on IE 6.0
but when i try to access http://localhost on Mozilla 1.6 it asks me for a
user name and pass word. I tried using my Windows user name and password but
it doesn't work. I also went to IIS on Administrative Tools to change the
security settings but stills doesn't work. Please help me with this issue.

Hi Karl,

As most people with IIS on a Pro machine are using it for
development, I usually recommend that they intentionally
set the root webserver node to require authenticated access
(so that it inherits onto all webs)

This is the standard install for web authors in our environment,
and it goes far in protecting a macine from poking and from
issues (not that there have been many new ones for a long
time now) that arise causing security patch releases for IIS.

It sounds like either the NTFS permissions of the web content
area are not set correctly for the configuration of IIS, or, that
the web(s) are set for authenticated access instead of anonymous
but you are not allowing clear text logins, or both.

Sounds like you've disabled anonymous authentication and have enabled
windows integrated authentication, which only works with IE on Windows. You
usually don't want to select this option unless you know what you're doing.
If these are public pages, choose anonymous. Or if you haven't disabled
anonymous authentication, it could be that you changed the password for the
IUSR account either in the Windows accounts database or in the IIS metabase
or disabled the account in some way, or changed the file permissions so that
IUSR no longer has permissions to the files in question [which is necessary
for anonymous authentication.

You may be able to see what is going on by enabling auditing on the relevant
files and looking in the windows security event log:

http://securityadmin.info/faq.asp#auditing

You can view and reset the IUSR account by using the ADSUTIL.VBS command:

http://securityadmin.info/faq.asp#iusr

Also, note that IIS 5.1 means you're running Windows XP, which is not a
great choice for a web server. With Windows workstations, you're limited to
no more than 1 to 5 concurrent users at any one time.

Actually Mozilla supports Windows authentication on Windows, starting with
1.7 IIRC.

You have good points, but I personally think there are reasons to consider
my approach as well. First, there are a fair number of IIS exploits that
work no matter what the authentication is set to, such as the PCT / SSL
vulnerability, so authentication isn't really a replacement for patching.
Second, changing the authentication method causes deviance between the test
and production webs, which could theoretically lead to surprises. Also, I
didn't want to assume that this person is a developer, who really knows. I
would personally rather change the list of permitted IP addresses to just
the local machine or subnet and make sure the machine is properly hardened
and frequently patched.
