Thanks for the hint of using mongrel_service 0.3.3. I get these log 
files now:

Not very helpful - OpenProcess fails with no apparent error.

Could you please explain what you want me to do ? I think I  have ran 
everything I can using psexec and as the actual service user (explained 
in my initial post). If there is something else, I will happily run it 
:). On the other hand, since it works using these two methods, no error 
message will appear. Only the service itself can not be started.

The app is a newly generated rails skeleton, and the user has "Full 
Control" on the directory and on the Ruby directory. I am not sure how I 
can get to the PATH variable when starting the service - any idea ?
