I tired the steps found at: http://technet.microsoft.com/en-us/library/cc774595(v=WS.10).aspx
I get to the list of certificats.....the list doesn't have thumbprints so I'm not sure which is the certificate that is producing the warning. I select a certificate that has expired. Try Renew with Same Key.
I get:
Enrollement Error The requested certificate template is not supported by this CA.
Where do I go from here?

a) you cannot renew already expired certificate. you can try Request New certificate. If you wanted to renew a certificate, you would have to do it before the original certificate expires
b) to see thumbprint, go into MMC console, certificates and open all the certificates one-by-one and lookup the thumbprints.

Here is a basic article for ADCS. Hope it can be useful to you.

OK. I found my CA - it is hosted on the same server that hosts Exchange. I do not have the Online Responder, or Web enrollment roles installed.
The link wanted me to change the subordinate certification authority to use a different template - "custom template". Currently it is using a template named SubCA. Do I need to change that to something else???

We can try the steps in the article below to use a custom template for Subordinate CA as a test:

I can do that.
1) Does it matter what I name the duplicate?
2) Does it matter if I choose Win 2003 or 2008?
3) Does it matter if I Publish in Active Directory?
4) Does it matter if I "Do not automatically reenroll if a duplicate certificate exists in Active Directory"? Since this WILL be a duplicate?
5) Does it matter if I use existing key for smart card certificate renewal? I don't use smart cards.
6) Do I need to have CA cerficate manager approval for enrollment?
7) Should I have authorized signatures for enrollment?
8) What are Superseded Templates?
9) Do I need to do anything with Extensions?
10) Do I need to change any of the default Security settings?
11) Once I am done, how do I tell applications to start using the duplicate template?
12) Why would this duplicate template allow me to create a new certificate for the one that expired?

dir cert:\LocalMachine\my | Where-Object { $_.HasPrivateKey } | Foreach-Object { write-host $_.thumbprint - $_.subject }This powershell command will help you to identify the certificate behind the thumbprint.

Thursday, July 19, 2012 11:56 AMI have a Subordinate Certificate AUthority. I'm still not sure WHY I need a copy of it nor WHAT to do with the duplicate copy. I'm also not sure what settings to check on the duplicate certificate.

After further review I added OWA to an existing certificate and deleted the offending cert.- Marked As Answer by JohnSLG Wednesday, August 22, 2012 11:59 AM
