I just dealt with a user who was unable to connect with XP and FTPX, but 
if they used the command line, it worked just fine. PASV mode didn't 
seem to make any difference. It's almost like the XP firewall doesn't 
keep ftp states. I use an iptables firewall to connect to the server 
(proftpd) and have 0 problems. When I had the user disable the windows 
firewall, it connected immediately. It's a recent problem, I have a 
feeling that MS changed the behaviour of the firewall recently, perhaps 
inadvertantly?

I recommended that the user try another firewall, but this seems like an 
 MS problem...
