I'm no SSIS expert. I'm just pretty sure, this has nothing to do with WinSCP.

Thanks for the reply Martin. Can you help reason this out?

I have access from that same account when I run the process from cmd prompt. I also have access from that same user when the scheduled task runs.

Right now I have a scheduled task that runs a BAT file that runs the script. This is a placeholder process because I can't get the project to run via the SQL Job/SSIS.

What would prevent network access from the SQL job/SSIS pkg? I'm using the same user for everything, which is also the user setup as the SQL Agent account.

It looks like your "SQL Agent Account" does not have a network access.

I know this is question is common, as I think I have read every forum post on the subject. I've been researching this issue for three days now.
I have checked https://winscp.net/eng/docs/faq_scheduler, and every other on-site article I can find. I'm either missing something small that's right in my face, or my problem is unique in some way.

I have a get file script that runs fine from cmd prompt, and scheduled task/BAT file, but will not run when initiated by a SQL Job/SSIS pkg. I set the entire process up on an a domain administrator account. The domain account is the same account as the SQL Agent Account. The account has full read/write access to all the file and directories referenced. I can also manually execute the SSIS pkg from within visual studio and the process completes fine. The only time it fails is when I execute the SQL Job that calls the SSIS pkg. I've tried calling WINSCP.com as well as WINSCP.exe.

At this point, I'm pulling my hair out. Any help will be greatly appreciated.
