Hi,
I have a WCF Service which connect to FTP opens directory and download the files from FTP Server and save into server.
When I run this service from asp.net development server it works fine without any error. But when I host this service on IIS and trying to call the service following error thrown by IIS.
425 Can't open data connection.
Can you please tell me why this is happening.
Thanks.

It seems that it could be security issue which is not identify your hosting server. The 425 error means that the data channel is blocked or closed between you and the server you are trying to connect.
