IE Loops when login authentication

[MARK]

Hi,
When trying to login into some websites, IE 6.0 goes into
a loop and brings me back to the login page again.

I have other pc using same IE version and I am able to
login to these websites fine.

I already deleted all cookies, did not help.
I check my advance setting for IE can not see anything to
check or uncheck....
Appreciate any suggestions.
--------
I did what Microsoft recommended, did not work. I am still
on a loop whe trying to login to certain websties.
