Different Notification Server computers within a hierarchy may manage different patch management language resources. The Patch Management Language Alerting replication rule ensures that child Notification Server computers only receive data and software update policies for their managed languages. This rule replicates information about the managed languages of the child Notification Server computer up to the parent. You must run this rule on a child before any attempt is made to replicate patch management data or software update policies. A parent Notification Server computer must manage all of the languages that its children require.
