CTIW fail (Assistant "se connecter à Internet" renvoit une erreur)

Bonjour,

A tout hazard, je m'adresse ici pour un probleme avec un windows serverr 2008 sbs.
Récemment installé, je dois obligatoirement (il me semble) passer par l'étape "se connecter à Internet" depuis un assistant automatisé signé microsoft. Hors, cela ne fonctionne pas et me demande de réexecuter l'assistant après que celui ci est échoué.
Après 1 journée de recherche, il semblerait que je sois seul au monde face à ce probleme.
Je joins le fichier journal ctiw.log au cas ou (c'est un erreur 8000007 non référencé évidemment)
