Im not using any 3rd party. I created packages using SSIS 2008 tested successfully in dev, deployed to file system, this was running for 2 weeks every day without any issues, no changes have been made on the SQL box. All other jobs are running without any errors

I have ran out of ideas, therefore, I have redeployed to SQL Server and modified my job steps to point to SQL Server instead of File System am now waiting for the job to execute.
