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
We are using IE6 on Windows XP
