Subject: msDS-HasInstantiatedNCs

In MS-ADTS nTDSDSA Object it says:

msDS-HasInstantiatedNCs: Contains an Object(DN-Binary) value for each NC replica that is hosted by this DC. The DN field is the DN of the root object of the NC. The Binary field contains the value of the instanceType attribute on the root object of the NC. This is a binary encoding of attribute instanceType with little-endian byte ordering. 

Requirement: The DN fields of all the values of msDS-HasInstantiatedNCs must be equal to the set of DNs contained in the values of msDS-hasMasterNCs and hasPartialReplicaNCs.


Who is the Requirement enforced by?  Is it a requirement that the client (the newly joining DC) set and maintain this, or that the existing DC being joined must maintain this?
