Here's the link to the forum post that helped me resolve the issue.
https://winscp.net/eng/docs/config#registry_key

I used the registry method. My scheduled task was running under anohter AD account created just for services and scheduled tasks. I connected to the SFTP server using the GUI under my account, which logged the key from the server in the registry. I then copied the registry key mentioned in the link to the other accounts user area in the registry. I could have also logged into the server under the other account and used the GUI to connect. This would have also stored the server key in the registry.

Nevermind... I found the solution in a few other forum posts.

WinSCP v. 4.3.2 build 1201
Windows Server Standard 2003 R2 SP2

When connecting to an SFTP server using the GUI Explorer interface, I can connect just fine. When I call an automated script from Windows Task Scheduler, I don't connect and the log file shows:

2011-09-27 15:06:04.479 If you trust this host, press Yes. To connect without adding host key to the cache, press No. To abandon the connection press Cancel.
. 2011-09-27 15:06:04.479
. 2011-09-27 15:06:04.479 Continue connecting and add host key to the cache? ()
. 2011-09-27 15:06:04.479 Attempt to close connection due to fatal exception:
* 2011-09-27 15:06:04.479 Host key wasn't verified!
. 2011-09-27 15:06:04.479 Closing connection.
. 2011-09-27 15:06:04.479 Sending special code: 12

My script file is:

@echo off
option batch on
option confirm off
open sftp://<username>:<password>@<host>.<domain>.com:228
cd /incoming
put d:\test file.txt
close

If I run the same script commands manually from a CLI, I can also connect and I never get propmted to accept the server key. How can I resolve this?

Thanks,
