HI MW67!
Scheduled task or Job, shows 'Replicated' status, in case if you have "Hierarchy" and you ran Job/Task assigned to clients, which are managed by Child Notification Servers. "Replicated" means that this Task/Job is also replicated and it will be executed on clients which are managed by Child Notification Server.
You can mouse double click on task status instance per client with 'Replicated' status and check what exact task/job execution status is on Child NS for this client PC.
Check on that Notification Server, whether you have hierarchy. Open Symantec Management Console -> Settings -> Notification Server -> Hierarchy -> open "Hierarchy Management" page.
