Case 1: The current certification authority certificate is affected

The certification authority always uses the latest, i.e. most recently installed, certification authority certificate to issue its certificates.

More information can be found in the article "The certification authority service does not start and throws the error message "The revocation function was unable to check revocation because the revocation server was offline. 0x80092013 (-2146885613 CRYPT_E_REVOCATION_OFFLINE)".„.

Case 2: A previous certification authority certificate is affected

If one of the previous certification authority certificates is affected, the certification authority service starts normally.

However, the Certification Authority will use the Event no. 48 log:
