[ms office - 2010] Prompting for Authentication

[LeightonJames]

Right, i'm fed up now lol.

 

I have spent weeks researching this issue with no joy.

 

Just recently we have started migrating all our schools over to Windows 7 Professional and Office 2010. This has all gone smoothly apart from one little hiccup.

 

Whenever a teacher tries to open an office document over the internet (not sharepoint) e.g. http://www.primaryresources.co.uk/ict/docs/ict_levels.doc they are requested to enter their network credentials as we are behind an authenticated proxy.

 

This is our setup:

Win 7

Office 2010

IE9

Authenticated proxy

Teachers have locked down profiles

 

I have tried numerous fixes such as changing BasicAuthLevel in the registry, adding the site to trusted sites/intranet sites.

 

Nothing seems to work. Even choosing remember credentials on the pop up.

 

Please don't suggest using a different browser as this is not a realistic solution (6982 computers over 76 schools).

 

Please can anyone help me with this?? I'm losing what little hair I actually have.

 

Thanks
