Hi Isham, Found on technet In Windows 2000, adding a new attribute to the global catalog causes a full synchronization of all of the domain data from all of the domains in the forest. In a large, multi-domain Windows 2000 forest, this synchronization can cause significant network traffic. Between domain controllers enabled as global catalogs that are running Windows Server 2003, only the newly added attribute is replicated.

Do the Windows 2000 domain controllers rebuild their global catalog partitions? 2. Do the Windows Server 2003 domain controllers not rebuild their global catalog partitions? What is the definitive algorithm?
