Questions regarding decommissioning an enterprise certificate authority in Server 2008

Hello Experts,

A couple of days ago my manager asked me to work on decommissioning our last Server 2008 domain controller.  While going through the server's configuration, I realized that at some point in time in the past, someone had installed the Active Directory Certificate Services role and this server has been issuing certificates.  Since certificate management is not something I have a lot of experience in, I have a couple of questions:
1.  What is the best way to stop this certificate server from issuing new certificates?
2.  In researching how to decommission a certificate authority, it looks like the process is to revoke the issued certificates and extend the life of the CRL.  If I revoke the certificates on this CA server, will the computers whose certificates have been revoked automatically get new certificates from our actual CA server?

Thanks,
Nick

Assuming you have a two or three tier hierarchy...

Yes, when you revoke a certificate, the member server will request a new certificate from whatever authority it is aware of.  Depending on how big your environment is, you might want to hit all hosts and look in their stores (scriptomagically) for the thumbprint on the cert you are going to revoke.  This may help you scope what your AoE is going to be.  Undoubtedly, you will have a small number of hosts which complain for one reason or another.  Typically forcing the request again using certutil or restarting the host will fix the issue, so long as your online responder, issuing CA(s) and GPO are all inline
