ZENworks Configuration Management 2017 Update 1
During certificate remint system update, during the pending activation phase, the following error is generated in zmd-messages.log running novell-zenworks-configure to activate:
[CertificateActivatorModule]  [Return Code :-1073741502]
In one case the primary server (Windows) was rebooted to correct the error on next certificate activation/verification schedule. When the activation is past due, the schedule runs very frequently. Look for [CertificateActivatorModule] in zmd-messages.log. Refresh the agent to trigger.
