This is a follow-up to the following thread:
I have created a credential and proxy. I then created a job with the one step being to run a specific SSIS task. On this step, I assigned the proxy I created as who the task should run as. I ensured that the account that was used has full control over the destination folder that the task will be accessing. I also gave the account the sysadmin role in the SQL Server database. The task fails when I tell it to run. The task failure refers me to the History log which contains nothing that helps me determine why it fails.
The task runs fine through BIDS. When I try and run it manually from the SQL Server using dtexec it fails with a "unable to access folder" error at the first file system task. This is why I am trying to run it using the SQL Server agent.
