What I've read from Microsoft ...

  • GC Partial Attribute Set (PAS)
  • In Windows 2000, modification required full rebuild of GC (full synchronization of read-only naming context)
    • When an additional attribute was marked for inclusion in the GC, all GC servers reset their USNs for GC attributes to 0 and rebuilt the Partial Attribute Set (PAS) from scratch
  • In Windows Server 2003, can preserve GC synchronization state instead of resetting
  • Propagation of PAS thus no longer results in full rebuild of global catalog partitions
    • Only the newly-included attributes are replicated- the PAS is not completely rebuilt

In a mixed environment of Windows 2000 and Windows Server 2003 domain controllers,

  1. 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?
