Export/Import/SQL Loader :: DataPump Succeeds But Dump File Does Not Get Created

datapump on Windows 2003/R11.2 I have a batch file that creates a daily dump of a schema in the DATA_PUMP_DIR - However, it doesn't! The script is as follows: REM Script to perform data pump export of the user01 schema and move to the

desktop.SET CURRDATE=%DATE:~10,4%%DATE:~4,2%%DATE:~7,2%SET CURRTIME=%TIME:~0,2%%TIME:~3,2%%time:~6,2%SET CURRTIME=%CURRTIME: =0%SET DATESTAMP=%CURRDATE%_%CURRTIME%SET DUMP_FILE=user01_EXP_%DATESTAMP%.DMPSETLOG_FILE=user01_EXP_%DATESTAMP%.LOGexpdp "sys/pwd@db  as sysdba" directory=DATA_PUMP_DIR dumpfile=%DUMP_FILE% schemas=user01 logfile=%LOG_FILE%  MOVE

For some reason when this is run from a remote server as a batch it fails to create a file although the output from the scripts has no errors apart from move statements and the expdp output is all good (it states that the file was created in the expected location).If the expdp command is run on the server itself it is all good.
