We have 3 Macs. The one running Tiger (10.4.11) can FTP a server with no trouble. So can my aging WindowsXP laptop using SmartFTP. But the two Macs running Leopard won't connect. I've tried everything in terms of configuring. It does connect to some sites, but one in particular it won't (even though the Tiger version can). I've been through as many configs with the client software and the Mac as I can figure...any ideas?
