# Per far scrivere il ritorno dalla chiamata di IIS nel file di log ho creato la schedulazione entrando con 
# l'utente stesso (Steamware) che esegue lo script e ho fatto import della schedulazione ( in ambiente ISE il log lo scrive )
# Ho messo anche permessi all'utente "Logon as batch job" ( vedi sotto )

# Utente messo in PowerUser e permessi scrittura cartella Steamware

# Logon as batch job policy is set for the user. This policy is accessible by opening the Control Panel, Administrative Tools, 
# and then Local Security Policy -> Local Policy -> User Rights Assignment -> then Logon as batch job.
