Integrated Windows Authentication

I am using Integrated Windows Authentication to protect a directory on a web
server. All clients connect and authenticate using MSIE using W2k or better.
It works fine inside my LAN, and on some other places outside my LAN, but on
some computers when I connect to the password protected directory (still
using MSIE), I simply get; "Error. Access Denied". These users can connect
to the main web server just fine- they only get this error when they try to
access that particular directory.

The error is not coming from my customized error pages, and the user does
not get a Windows password prompt. Just the error. There are no access
priveliges denied on the web server or on the firewall to this web server or
directory.

Does anyone know if this is a client-side or server-side issue, or if there
is a way to fix this for my users?

Thanks in advance for suggestions/solutions.

If these machines are connecting through a firewall or proxy, then that's
the problem. Integrated Authentication is not designed to work in that
environment.
