RE: [ActiveDir] GC partition rebuild algorithm

[Dean Wells]

Assuming both 2000 and 2003 DCs are present within the forest -   * 2000 GCs WILL full sync. * 2003 GCs will NOT full sync. assuming     - they have a connection object representing a DC in the foreign domain that is also running 2003     - if multiple domains exist, it depends on the OS of the DC from which the GC sources THAT partition   In short, 2003 GCs will incrementally sync. from other 2003 DCs and will full sync. from 2000 DCs.   Dean -- Dean Wells MSEtechnology ( Tel: +1 (954) 501-4307 * Email: dwells@msetechnology.com http://msetechnology.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Isham, Alan A Sent: Friday, December 19, 2003 7:31 PM To: [EMAIL PROTECTED] Subject: [ActiveDir] GC partition rebuild algorithm 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, Do the Windows 2000 domain controllers rebuild their global catalog partitions?  Do the Windows Server 2003 domain controllers not rebuild their global catalog partitions? What is the definitive algorithm? Alan A Isham  Messaging and Active Directory Engineering Intel Corporation in Folsom, California
