Net use on scheduled bat

I have this bat file scheduled in a windows server 2008 r2:

net use \\ip\share\employees\ /user:domain\user password
robocopy C:\Zucchetti\Timbrature\sicurezza\ \\ip\share\employees\ Timbrature_Giornaliere_5min.csv /R:0 /W:0 /v > C:\Zucchetti\Timbrature\sicurezza\logcopia.txt
del "Timbrature_Giornaliere_5min.csv"

If I run the bat manually the it runs fine. If I run the bat scheduled with windows server 2008 task scheduler wether the user is logged on or not I get the following error in the log:

-------------------------------------------------------------------------------

How could I make it work in a scheduled bat file?
