Hi, just been testing subordinate CA on my Windows Server 2008 Enterprise server, and the green bar was not showing on our internal EV certificates issued by the root ca, after uninstalling Certificate services it still does not turn green. Any ideas?

Hi, Thanks for posting in Microsoft TechNet forums. As far as I know, the issuing CA must be a minimum of Windows Server 2008 R2 to be able to issue EV certificates (internally or externally). If the issuing CA is a Windows Server 2008, that can be the cause of the problem. Here are some links for your reference: Extended Validation support for websites using internal certificates http://blogs.technet.com/b/askds/archive/2009/08/14/extended-validation-support-for-websites-using-internal-certificates.aspx Everything you wanted to know about Extended Validation but were afraid to ask http://blogs.technet.com/b/instan/archive/2010/07/12/everything-you-wanted-to-know-about-extended-validation-but-were-afraid-to-ask.aspx Certificate Properties Extended Validation Tab http://technet.microsoft.com/en-us/library/dd759060.aspx Regards Kevin

Hi, the issuing ca is windows server 2008 r2 and all computers and servers recognise the ev certificate. But when I installed certificate services on one of our servers, the green bar stopped showing. I have removed it cert services and it still won't go green. will have a look through links to see if they provide info.
