Hello Gary,
Initially, we suggest you to check the *.bat file by running it from the command line.
If it runs successfully rom the command line, move the *.bat files to the Veritas directory :\Program Files\Veritas\Backup EXec\NT\*.bat and verify the results
We hope this helps you.
Thank you, if you still face any issues with running the pre-job command then do let us know.
