Upgrading server certs through CA on Active Directory

I am trying to change a template or replace it that Active Directory CA holds.  Currently my test server (Server 2003) is being issued a cert that is 1024 for Client Authentication and Server Authentication.  I want to change this to 2048.  Since the CA controls this I need to perform it their and then have this pushed out.  How do you change the template used so that the servers will get a new 2048 cert and AD CA knows to use this updated template.

This is by design. If you are using an internal CA when you need to do is create a new template and re-publish it. You cannot modify per-existing templates that are already in the environment. You need to publish new ones. See Screenshots below...

Thanks Will.  So after doing this how do you tell the CA to not use template A(original) and start using Template B(new copy using 2048) for the server or servers?

If you reference one of the screenshots you need to "Revoke" the certificate and then issue the new one you created.
