Another question:
6° In DNS zone _msdcs, at root, there is one DNS record per DC. These
records are those which have to create manually and are rlated to
objectGuid as explained there:

I have for now 4 DC in my second site, two of them have 2 records when the
2 others have only 1.
These additional records are <DC related objectGuid>CNF:<another uuid>

<another uuid> is not the same for these two records. These two records are
related to 2 different DC.

Are they supposed to exist? If yes aren't they supposed to exist for all 4
DC in this second site?

Best regards,
