The Microsoft FTP service does not support SSL in any of its versions to date.

If you want to use SSL secured FTP you will need to move to a different FTP server product.

Sorry.

Dave, this is interesting. Is it possible to use IIS web server for FTP with SSL by using any interface that you know of?

Thanks,
