site login issue with IE 6 and Win 98

Thousands of people log into this site by browsing to the URL and filling out a username and password in a basic authentication box that pops up. For one particular user with IE 6 on a Win 98 box, this doesn't happen--the browser just bypasses that box and tries to log into the site. I've had the user turn off Auto-Complete and clear all that, as well as clear cookies and temp internet files and reboot, but still no luck. Any ideas???

What happened was they probably said:
Remember this password and IE will do this.
I have users that have this problem, I normally have them do the following:
Goto Internet Optionts --> Content --> Auto Complete --> Clear Passwords
and you might need to
Clear the cache and cookies
See if that helps...

Thanks--I've seen that problem aplenty, but I had him take care of all that, and still no luck.

Did you have them uncheck all of the boxes under the autocomplete to see if that works?
You can try to do this:
look under advanced-->scroll to security header...
under that it says "enable integrated windows authenication (requires restart)" make sure that is unchecked
requires restart means close all open browsers so the setting takes place, not a total operating system restart...

Yeah, I did clear all that Auto-Complete junk, but I didn't know about this other setting you mentioned.
