ZENworks prompts you to change your ZENworks zone certificate 90 days before the expiration of the certificate. The following warning message is displayed for each administrator once every 24 hours after the administrator logs in to ZENworks Control Center:
The certificate on hostname_of_the_device will expire in number_of_days days.
The message is displayed for every server and zone whose certificate is about to expire.

You should re-create the certificate before it expires because recreating a certificate after it expires is a very cumbersome process that involves performing manual tasks on each device in the zone.
The information provided in this section is applicable for Windows and Linux platforms.
To re-create the zone certificate before it expires, review the following scenarios:
IMPORTANT:ZENworks 11 SP3 currently does not support changing the external certificate to an internal certificate on Primary Servers.
