> I did the checks you recommended and i found where is the creation of the dNSHostName attribute.
> When i do a dcpromo the server that i am joining to isn't responsible for creating the dNSHostName for my Server entry. After i finish the dcpromo process there isn't a dNSHostName entry set on the server that i join to, but there is an entry set on the server that is joining to the domain. This entry is then being promoted to the first DC during replication. The update of the dNSHostName attribute happens during dcpromo and exist only in the db of the joining server. The attachment is the proposed fix for this.
I think we should do this before the ldb_transaction_prepare_commit() in
so that it happens inside the transaction.
