    Hi,
    To know the issue more clearly, would you please confirm the following information:
    1, Is your environment a 2 tier PKI or one tier PKI?
    2,The damaged CA is a offline CA or an enterprise CA (Issue CA)?
    3,If the old PKI is not used any more , we 'd better remove the old one ,and then install a new CA,
    To remove the Orphaned Certificate Authority from AD, refer to the steps 5-9 in the following link:

    To create a new one tier pki or 2 tier pki, please refer to the following links:
