On the server end, the logs show that we're manually disconnecting after a short period of time, so it's hard for me to say its the server's fault either. My guess at this point is an incompatibility with FileZilla server and WS_FTP Pro 2006 client. I've tried toggling PASV mode, among other things, but the issue occurs with the same regularity.</P><P>Any suggestions for what I should try next? I'm all out of ideas.Wed, 18 Jun 2008 11:18:10 GMTtigreye007
