I have found what i think was my problem. I was setting my service to interact with desktop (I had an icon in the tray...). I tried to set it withoit interaction and it worked.

As far as I know. it was running as an NT service.

Yes.

So... I have less control on my service but it work. I just found that it is important to have a good logging procedure. Tanks you all for your help.
