The SSIS job runs as the SQL Agent Account which is SQLSERVERAGENT. If it fails under that, I then try to run as a proxy user account that has admin rights on the box. When this problem occurs both fail. If I log on to the server with the admin account and then log back off. The job runs fine as SQLSERVERAGENT or the proxy account. In testing I've removed everything from the registry which shouldn't be needed since it reads the ini file so then I cleared everything there so that only the script is read. I can't determine from the logging why it's not connecting to the server to do the initial handshake without that odd login. FYI - There is no firewall on the server but there is a hardware firewall.
