Environment
 ZENworks Configuration Management 2017 Update 1
  
Situation
 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] 
  Resolution
 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.
