Browser error "Malformed certificate"  = Google Chrome (v36) and IE (v8) - with a root CA SHA256

Using Google and IE to connect to a URL we get an error :-
The certificate that Chrome received during this connection attempt is not formatted correctly, so Chrome cannot use it to protect your information.
Error type: Malformed certificate
Subject: mycert.testing.com
Issuer: GlobalSign Organization Validation CA - SHA256 - G2

The server is running WIndows 2003 server and the version of browsers as stated above. So on a development 2003 server I ran Windows updates and re-tried and the issue was resolved. I need to fix the issue on live 2003 servers but I do not want to run the complete Windows Update in case it breaks many other functions.
I am assuming there was an upgrade to support  new hashing algorithm SHA256 ?
Appreciate if anyone can shed light on this and more specific on what needs updating.

Thanks

Look for the Root Certificate Updates and see if that fixes your problem.

I am still struggling to find anything that fixes the issue. There seems to be a common theme with the SHA256 in the certs needed within Windows 2003. I fixed the issue by running Windows updates on the 2003 server but this tkes over 4 hours and there are many. My other issue being, this is a live server running apps and web sites and it woudl break other apps and be down for 4 hours.
SO I am not ure what Root Certificate as part of the update is required. I woudl be grateful if you know what update is required.
I found this link http://support.microsoft.com/kb/968730
But when I download it and attempt to run it, it says " but is for a machine other than the current machine" so does not run .

YEs I found that one and applied it made no difference. I even got the new RootCA Intermediate CA and imported into the Server Certificate MMC made no difference. I have been sent a knowledge base KB968730  

Applied it , re-booted and it seemed to have fixed my problem. I am going to have to do some more testing on other server
