Our website runs on a Windows 2003 server using IIS. Anonymous access is
enabled on the default website with a domain user account that has
administrative rights to the server. Integrated Windows Authentication is
also checked.

Users on our LAN connect to the website on the server with no problem
(meaning, they are not prompted for a username & password).

However, if you try to access the same website from a Terminal Server, you
get prompted to enter a username and password.

Can anyone suggest ways that authentication is either not required at all,
or at least invisible to the user? This web server is only used internally,
so we don't need super high security.

Thanks,

Jason

Hi Jason,

If you want anonymous connection to work, make sure that user account that
is assigned for anonymous access has read permissions on the web content to
the site. It looks like right now the anonymous account does not have NTFS
permissions...

IIS will always honor the NTFS permissions...

Also -- you should not grant administrator permissions to anonymous account.
It can be very dangerous for security of your server...

Thanks Mike, but since the anonymous account has administrator permissions
not only to the website, but the server itself, I would not think that the
problem is a permissions issue? At least as far as the Anonymous Account is
concerned?

Hi,

I don't know how permissions are set on the folder where your web content is
stored. My advice is to first check that this user has permissions (at least
read) on the folder where the web content is.

You can lock out even administrator from the folder - the only difference is
that administrator (or member of administrators group) can take ownership
and with it permissions to the folder.

The user has full control permissions on the web content folders, plus admin
rights on the machine.

Hi Jason,

If the server has been applied with SP1, the familiar cause is the new
loopback check security feature. Please take a look at the following
article:

896861 You receive error 401.1 when you browse a Web site that uses
Integrated
http://support.microsoft.com/?id=896861

Another possible cause is there are 3 group policy permissions may be
missed by the IIS anonymous - IUSR account. You should check them in the
server's local security policy and your domain security policy on DC:

- Access this computer from the network

- Log on locally

- Log on as a batch job

Refer to:

275167 PRB: Anonymous access fails with an HTTP 401.1 error after you join
an
http://support.microsoft.com/?id=275167

Please let me know how the thing is going. Thanks.
