I've come across an interesting issue, when I try to open up a document(any document but mostly word) I get prompted to enter a set of credentials from Windows Security. It wants me to enter my credentials for my schools Blackboard Vista site, I have done this and nothing seems to work. However, I can simply click on the cancel button and the document opens up. I have tried this in other browsers and this issue is only occurring when I use IE8 and Windows 7.
I know its not the Credentials Manager in Windows 7 so I figured it has to be a setting in IE8. Has anyone else encountered this issue and have you found a resolution for it?
Yes, this is a known problem. There's a long article about it from the administrators point of view in the support area, but the underlying problem is really a Microsoft one, and I don't really see any solution or workaround mentioned:
