When I attempt to open some secure (https

web sites in IE, I am
re-directed back to the login screen, this does not hapen with every site,
and sometimes a site will work fine, and othertimes, it does not. I have
tried everyting that I can think of, with no success. I am not the only one
on our company that is having this issue, and nothing has changed in our
enterprise, so I am not sure what the cause is.
We are running IE 6 SP2
Both Windows 2k and XP are having this issue.
Both Users and Administrators are having this issue
I changed IE's settings to "Except all cookies" with no luck
I added the site to the "Trusted Sites" in IE and still nothing.
Any advice that anyone could provide would be appericiated
