Having a little problem with Windows Integrated Authentication on IIS 6 on
W2k3 Std SP1 and wondered if anyone has an idea as to what is wrong, as I
cannot find anything.

I have an IIS site with just one page, default.htm, as a test webserver.
This server will require secure access in the future when it goes into
production.  When I enable WIA  (no other authentication is enabled, no
annoymous access) any user that attempts to access it is asked for their
credentials.

All users are in the same domain as the IIS server.
All users have access to another IIS server that also uses WIA, but are not
asked for username and password when accessing that site - it just logs in
as you would expect it to.
All users use IE6 and have enable windows authentication ticked in IE.

Anyone have any ideas?

TIA
