Its common that sometimes few admins miss the renewal of some key certificates in their Microsoft internal PKI (Public Key Infrastructure), this is due to the fact that its a bit of manual task and you need to set manually some Outlook reminders (My favorite method) or run schedules tasks to remind you before the Certificate expiration date.
However if you a user that logs frequently on this CA (Certificate Authority) server we can enable Auto Enrollment for this user. After configuring it, we don’t need to worry about the expiring certificates as long as the specific user still logs onto the CA.
To Enable Auto Enrollment you need to do the following:
This user with the Autoenroll feature enabled when logged in on the CA server will get notified and the certificate will get enrolled and the Certificate won't get expired.
