Some replication related problems existing in Windows 2000 have been addressed in Windows .NET. Primarily, this concerns the enhanced linked value and Global Catalog replication as well as algorithms used by the Knowledge Consistency Checker (KCC) for generating replication topology in forests with large number of sites.
Linked value replication reduces network traffic when group membership is changed: only new or deleted group members are replicated instead of the entire list of group members stored in the member attribute. This is essential for groups with a large number of members.
In Windows 2000, when a new attribute is added to Global Catalog, a full synchronization of partial replicas is required, and this process affects all domains in the forest. In a Windows .nEt, only the new attribute is replicated to Global Catalog servers.
