In my company we have a problem with one of our websites. It cannot be accessed with https in IE7 and IE8 when users have PC's running XP. Firefox is working fine, but the users come from organisations where IE8 is standard browser software and XP the OS used currently.
When I include IE7 it is because I have tried to hit F12 and run the browser in IE7 mode to see if it worked. Not working. The site is running on IIS7.5 on a Widows 2008 server and is Net Framework v4.0, Classic Mode.
It is a new version of a system where we also have a site using the old version in v2.0, Classic Mode. It can be accessed without problems. but I don't know if that is relevant or not.
The sites are running on subdomains and the SSL certificates are associated with the subdomains.
I have googled the problem and can see that there can be problems with IE8 and XP. Have tried some of the solutions suggested but so far nothing has worked.
I hope very much that somebody can help. We have some users that must finish registrations in our systems very soon.
