Unable to logon to HTTPS site

I have a couple of users who are unable to log on the certain HTTPS sites.
They are prompted to enter their usernames and password which they do but the logon box just prompt them to enter their username and password again. They do this three time and then receive the error message ‘Proper authorization is required for the administration of this proxy. Either your browser does not perform authorization, or your authorization has failed’

If I log on to their PC I can access the site using their username and password with out problem. If they log on to a different PC they still have the same error.

I have tried changing numerous internet explore setting but can not find one which solves this problem

Hurel,

Seems like a user profile issue.  Your profile will work on their PC, but their profile will not work on other PC's.  Create a new Windows XP proifles for the two users.

I've already tried all the trouble shooting in the links provided. Thanks anyway.
I know I could just create two new profiles but that doesn't solve my problem long term.
I could create two new profiles and get the same problem a few days down the line.
There must be something stored in the NTUSER.DAT stopping the authorization process.
I have loaded the NTUSER.DAT hive into the registry but do not know which bit would need to be altered to correct this problem or if there is another way to solve it
