how to ensure my Root Certificate authority got renewed ?

Hi

I renewed  our root CA  certificate  today based on the below mentioned TechNet steps.

To renew a root certification authority

1. Log on to the system as a Certification Authority Administrator.
2. Open Certification Authority.
3. In the console tree, click the name of the certification authority (CA).
   
   Where?
   • Certification Authority (Computer)/CA name
4. On theAction menu, point to All Tasks, and click Renew CA Certificate.
5. Do one of the following:
   • If you want to generate a new public and private key pair for the certification authority's certificate, clickYes.
   • If you want to reuse the current public and private key pair for the certification authority's certificate, clickNo.

Note

• To open Certification Authority, clickStart, click Control Panel, double-click Administrative Tools, and then double-click Certification Authority.

I selected the option  use the current public & private key pair  option. after that it renewed the Root CA Certificate.

1. How to ensure that my Root CA got renewed?

2. is the Renewed certificate will automatically  reflect in all our member servers (like exchange,sharepoint,lync),  AD clients?

awaiting for your valuable reply.
