Why is access denied when copying Robocopy from TaskSheduler?

Question

System administration

Good afternoon, when trying to copy files from the local drive D:\backup\%date% to the network drive \\192.168.3.182\backup\week\%date% robocopy gives
ERROR 5 Getting File System Type of Destination \\192.168 in the log. 3.182\backup\week\30.07.2015
Access is denied.
In TaskSheduler in Action it is written to execute a cmd script. There is one line in the script -
robocopy D:\Backup\%date% \\192.168.3.182\backup\week\%date% /E /NP /Z /R:20 /W:60 /LOG+:D:\log.log
