NTSVC and Windows NT4

Bonjour,
J'ai essayé d'utiliser NTSVC dans mon application afin de la
faire executer comme un service de Windows. Si je fais rouler mon
application sur un ordinateur où il y a VB, ça fonctionne bien. Si par
contre je la met sur un ordinateur avec Windows NT4 SP6a fraichement
installé, ca ne fonctionne pas. Est-ce que quelqu'un pourrait me dire ce que
je fais incorrectement (le code suit) ?

En fait, on dirait que l'événement NTService_Start ne remonte jamais et je
ne sais pas pourquoi.

Merci

Voilà le Code:
