I'm tasked with downloading data from a server on a remote domain that only used windows authentication. This download has been done manually by someone for well over two years (thankfully not by me and I feel for the poor soul who has been doing it) and is high on my management's priority list.
I have been given a domain account on the remote domain and we have set up our domain with a limited trust, so I can run BIDS with \runas.exe /netonly /user:<domain\account> and sucessfully download the data.
Now that it works, I want to schedule this download so I created a credential with the remote domain account and a proxy and set up the job to run the SSIS package with SA and set the runas option in the package to use the proxy. It fails with the following error:
Unable to start execution of step 1 (reason: Error authenticating proxy <domain\account>, system error: Logon Failure: The machine you are logging onto is protected by an authentication firewall. The specified account is not allowed to authenticate to the machine.). The step failed.
Any ideas on what I may be doing wrong or if there is another, possibly better, way to approach this?
