Winscp error "Network error: Socket operation on non-socket"

I am trying to use Winscp on Windows 2003 server, to connect to a linux system running SSH.

I am able to connect to this particular linux system by using Winscp from any other system running windows XP or windows 7.
However when I try to connect using Winscp on windows 2003 server system, I get a dialog box with following message

"socket operation on non - socket", and the operation fails.

Has anyone come across the same error? Is there any solution for the problem ?

below is the content of the session.log file

Re: Winscp error "Network error: Socket operation on non-socket"

Haven't seen the problem before. Are you able to connect with any other SSH client?

No I am not able to connect using other clients also, I think the reason could be
because of some firewalls setting on Windows 2003 server. I shall try to figure out as which are the security setting on Windows 2003 server blocking access to use the ssh client service, and then try to connect.
