    Hello Vishnu Priya,

    Thank you for posting in Q&A forum.

    You can check all the certificates issued by CA in the "Issued Certificates" container on both root CA server and issuing CA server\ Certification Authority console (below).

    And you can also check if you set up certificates autoenrollment via GPO.

    For more information, please refer to links below.
