Can anyone help? Our Intranet runs on IIS 5 on a Win2K server (it's a mostly PC network, before anyone suggests changing servers :-)), and it uses Windows authentication to prevent unauthorised access. For most of our Mac users this is no problem--when they try to access the site using Internet Explorer it pops up a password box where they can type their username, password, and domain, and they can get onto the Intranet just fine.
One machine, however, is different. The password box comes up just as it should, but whatever the username/password typed in a 401 (Access Denied) page is always returned. I've looked at the IIS logs and it's as if the browser isn't passing on the password information. It's definitely a problem with that specific machine, because the user of that machine can access the Intranet on any other Mac using his username and password.
Anyone encountered this before, and if so, what's the solution?
Oh, the Mac in question is running OS 9.1 with Internet Explorer 5.1.4 installed.
