When I try to connect to a linux workstation from my windows XP desktop, WinSCP now returns the error message "Host does not exist". It use to work fine. Ping still works from my windows machine, and I can still ssh to the workstations when using PuTTy with no problem. The host name resolves without a problem. When I try to connect with WinSCP directly using the IP address, I get the error, "Connection Refused". If I try using WinSCP from my laptop (another winodows XP box), it works fine, so I know that my SCP server is working fine. I tried turning off the Firewall in windows on my desktop, but I still have the problem, and it shouldn't be an issue becaues PuTTy/ssh works fine. I tried uninstalling and reinstalling WinSCP and PuTTy, but the problem still persists. Any idea what may be causing the problem? Thanks.
