WinSCP installed on Windows 2008 R2 fails to connect to target machine

WinSCP installed on Windows 7 on Personal Computer connects to target machine but
WinSCP installed on Windows 2008 R2 OS on virtual server fails to connect to same target machine using same logon credentials.

Using WinSCP 5.7.6 with “Commander” interface on both Window versions.
File Protocol is FTP with TLS/SSL Explicit encryption, port 21

Error message states the target machine actively refused connection on 2008 R2 server. I checked with our network administrator and neither Personal Computer or virtual machine have any blocking firewalls.

Might you have any ideas why WinSCP does not work on Windows 2008 R2? Thank you.

Are you able to connect with any other FTP client?

Please attach a full log file showing the problem (using the latest version of WinSCP).

Prikryl,

Thank you for replying to my inquiry. Attached are log files from both Windows 2008 R2 (failed) and Windows 7 (success). Your expertise is much appreciated.

Thanks for the logs. Though, are you able to connect to the FTP server anyhow from the 2008 machine?

We installed WinSCP on another computer with Windows Server R2 and it connects to the target machine. We are not going investigate why it does not work on the server where WinSCP fails to connect to the target machine. The WinSCP configuration settings are the same on both servers.
