Got an XP pc running Core FTP. Uploads take forever if they work at all. If I run it from the command line, ftp works normal and fast. I have 5 other XPs in the same office all connect to an SBS 2008 server and all can ftp normally via Core FTP or Filezilla. So can a Vista computer not connected via the server. On this one pc, neither Core FTP nor Filezilla works. In fact, Filezilla does nothing at all. It lets you configure the ip address and everything else, but nothing happens. Nothing. I removed & redownloaded both programs, rebooted and tried again. No luck. I tried disabling virus protection and some network programs like Skype etc. No difference. The settings are identical on Core FTP to all the other computers which work. Passive mode is unchecked. Any suggestions? I can try yet another free FTP program or teach the user how to use the command line ftp, but it's so weird. If it was a network issue or firewall or something, why does the command line work on the same pc, but not via these ftp programs?
