    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.

    Thanks.  I saw that thread and, unfortunately I don't understand it.  I'm going to have to take a course on certificates.

    Hi John,

    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???

    Hi John,

    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    8) What are Superseded Templates?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?

      Has Code
    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.

    I 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.
