Lync Server 2013 CA Request Configuration Issue on Windows Server 2012

Heyas,

When Choosing a certification Authority for the Lync Server following the guidelines of the following document: http://windowspbx.blogspot.no/2012/07/step-by-step-installing-lync-server.html

I get the following warnings on the Certificate Request - Executing Commands screen.

Create a certificate request based on Lync Server configuration for this computer.
Issued thumbprint "1650D388DBD7E1E8CF3291E58943FACFDC7C8809" for use "Default,WebServicesInternal,WebServicesExternal" by "winsvr-dc.labs.local\labs-WINSVR-DC-CA".
 WARNING: The chain of the certificate "1650D388DBD7E1E8CF3291E58943FACFDC7C8809" is invalid.
No changes were made to the Central Management Store.

 WARNING: Detailed results can be found at "C:\Users\administrator.labs\AppData\Local\Temp\2\Request-CSCertificate-[2013_12_27][10_43_13].html".

Could anyone enlighten me as to what is going on,  I am running Microsoft Lync 2013 on Windows Server 2012.

Thank you.

Hi There,

Do you have internal CA ? and can you check if you have root ca cert and intermediate cert pushed into local computer cert store? If not then add it.

This is a warning not an error, so this step would have completed with warning. Basically what that error means is that your certificate chain is not valid i.e. root ca -- intermediate ca-- issued certificate.

Can you manually check the certificate from mmc and check if it's valid and if it has got the private keys?

Hi V-2nas,

I am complete Windows Server 2012 noob, I need some clarification.

How do I check if I have an internal CA?
How do I check if the root ca cert and intermediate cert pushed into local computer cert store
How do I manually check the certificate from MMC and check if it's valid and that it has private keys.

Thank you.
