after first installing windows xp and putty, i could ssh onto my server no problems, but all of a sudden i've started getting "connection refused" whenever i try and connect using putty on windows xp. If I reboot my PC into linux, I can ssh onto my server as usual with no problems, so this seems to be a Windows XP issue, does anyone have any ideas what this could be? I've searched the archives but cannot find any clues.
