SQLCMD Batch File Issues

Trying to get a sqlcmd bat file to work. Basically it is just dumping info to a .txt file stored on a NAS. Works perfectly if pasted directly into a cmd prompt but if executed via a batch (aiming to have this be a scheduled job) I receive an error (listed below). The service account I am running the script as has SA rights to the DB.

Any help would be much appreciated...

SET MY_PATH=C:\Program Files\Microsoft SQL Server\100\Tools\Binn
SET SERVER=SERVERNAME
SET DB=COMPANY_REPORTS
SET INPUTFILE=C:\scripts\COMPANY_REPORTS_SQL\ReportScripts\Script_ProjectTracker.sql
SET OUTPUTFILE=\STORAGE\LOCATION\FOLDER\DATA.txt
"%MY_PATH%\SQLCMD.exe" -S %SERVER% -C -E -d %DB% -s"|" -h-1 -W -k -i %INPUTFILE% | %windir%\System32\findstr /V /C:"-" /B > %OUTPUTFILE%

ERROR OUTPUT:
Msg 4060, Level 11, State 1, Server SERVERNAME, Line 1
Cannot open database " COMPANY_REPORTS" requested by the login. The login failed.
Msg 18456, Level 14, State 1, Server SERVERNAME, Line 1
Login failed for user 'DOMAIN\SERVICEACCOUNT'.

  1. Verify that the service account has read access to the database (the job is being run under the service account, not sa)
  2. perhaps setup a proxy login for running this job and give it access to the database and to the files in the filesystem
  3. Add a drive letter to the OUTPUTFILE Set statement
