scheduled batch script fails

hi i have a batch script in my schedule task that fails when its suppose to run. I did some troubleshooting and it doesn’t seem to like the the mapped network drive. what the scrip is doing is copying files to the network trough a mapped drive. i can run the batch file manually but when it runs on schedule it fails, saying 0 files copied.

any ideas how i can get it to recognize the nework mapped drive?
by the way i changed the network drive letter in the script to the local hard drive and it executed fine.

thanks,
