using NET USE when not logged

Hi
I'm having problem when trying to use AUTOEXNT.EXE service application (find in NT4 ressource kit).
I define a service that is automatically started at boot time (not logged). This service is trying to copy files from current local computer to remote computer localised on local network area (\\PCNT12 for example). I used service concept in order that the application can work even if user is not connected.
I follow the procedure described in autoexnt.txt but I can't find the way to 'mount' remote shared hard disk space (using net use) even if not connected.
could you give me an answer of the exact procedure to follow (in order to NET USE command at boot time) ?

Thanks.
