2.7.1.5 Group Policy Failures Related to Active Directory Replication

In a single DC domain, there is no impact on Group Policy that is associated with Active Directory replication. However, in multiple-DC domain scenarios, directory replication introduces a time delay that can defer the application of Group Policy in a domain until all data is successfully propagated to all DCs. During this delay period, earlier modifications to Group Policy configurations are not applied to policy targets in replication domains. Group Policy administrators should note that this is not an error, although it can appear to be an error.

However, if Active Directory replication actually fails, Group Policy continues to function normally in its pre-existing state, but any updates to Group Policy configurations are not applied until a successful replication occurs and the delay period has expired.
