I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Sounds like it may be a setting in the security GPO or in the security of 2010.  Denying access to hyper links is becomeing more "default" than it used to be.
This can happen sometimes when browsers mess up the registry entries and confuse as to which is the default.

This can sometimes be fixed with doing a reset of the web settings in Internet Explorer or setting your browser (IE, FF etc) as default.

Has this started happening since installed / Uninstalling either Firefox or Chrome?

IE8 on some of these workstations and laptops had been manually upgraded to IE9 which caused some issues with our ERP application so we uninstalled IE9 and reverted them back to IE8.  But the this problem does not exist on all workstations that had this procedure completed on them.  That is why it is a mystery.  I reset all IE settings to Default but still have the same problem.  It is not a GPO issue as it only affects a small number of devices all configured identically; however, they all have Office 2010.  No problems with Office 2007.

Try importing the following rgistry key from a machine that is working...

Another option would be recreating the registry key mentioned in this MS Article:


Export it from a machine that is working and import into the registry on a machine that has the problem.

You could also try copying the following to a notpad file and saving it as <filename>.reg and importing it into your registry.

"Content Type"="text/html"






"Content Type"="text/html"

I have attempted all recommended solutions; however, the problem is recurring.  We decided it is much faster and efficient to Ghost the affected machines with a fresh image.  Problem solved.  Thank you all for your recommended solutions.

It is my opinion that the problem was being caused by something other than what I may have described.  I strongly feel that the recommended solutions would have worked well if the registry issue was the problem.  Since we re-imaged the machines, we have no way of knowing what the exact problem was unless it resurfaces again.  I appreciate and thank both experts for their carefully thought out solutions.
