Résultat étrange de Dcdiag

Le
JF
Bonjour,

1 domaine - 3 sites - 4 DC Win2k3, mode 2000 natif. (Sur Site1 j'ai 2 DC) .
Tous ces DC (sauf "Site3Server1"il était déjà à 2k3) ont été migré à 2003
depuis les 6 derniers mois. La réplication se fait très bien, ils sont tous
DNS et aucun serveur ne génère d'erreurs de réplication/DNS/system. Si je
fais des changements dans AD sur n'importe quel site le changement est
répliqué sur mes 4 DC. Par routine, j'ai fait un dcdiag sur l'un d'entre eux
et j'obtiens le résultat suivant :

Je ne comprends pas. Surtout qu'il dit "passed test intersite"

Et si je vais dans AD sites & services, sur chaque site, dans NTDS site
settings properties, le "Inter-Site topology generator" porte bien le nom du
bridgehead pour ce site. Par contre plus bas dans ce même écran j'ai
l'avertissement suivant :

"Auto-generation of Active Directory replication topology between this site
and other sites is disabled."


Quelqu'un pourrait m'éclairer? Il y a quelque chose que j'ai dû louper

Merci à l'avance

Le #1163556
J'ai trouvé. Dans adsiedit.msc dans "NTDS site settings" de mes sites il y a
l'attribut options. Il avait la valeur 16, ce qui signifie de désactiver le
ISTG. En effaçant cette valeur sur chacun de mes sites tous les messages
d'erreur de DCDiag disparaissent et la synchro de la topologie se fait à
nouveau.
