Network error: Software caused connection Abort

We're having trouble connecting to an ftp server. I'm able to connect from another server on the same network, I'm able to connect from my local machine at home. But this one server keeps throwing the error...
Error: Network error: Software caused connection abort
Error: Could not connect to server

I tried re-adding credentials, deleting the SSH record in registry for the site, I even completely uninstalled WinSCP and re-installed, no luck. Then I tried another ftp client, still no luck. I get the same error whether I use the client or the command line.

I'm hoping someone may be able to help out... here is our log...

Re: Network error: Software caused connection Abort

So is it FTP server or SFTP server? You write about FTP, but connect using SFTP. What protocol are you using on the machines, where you can connect?

Can you connect using any other FTP/SFTP/SSH client from the machine, where WinSCP does not work?
