No, I can not reproduce any passive problems locally with a server on my development PC, or my local Windows 2000 server, or by accessing the offending FTP server over the VPN, 100 files uploaded without error. So I've made the passive port change in the FTP server, and installed it on the offending server, need to wait for the logs tomorrow to see if the remote clients are happier. I suspect the real cause of the problem is one of the Sonicwalls, FTP is always trouble with firewalls (even without NAT issues), yet these passive errors occur much less frequently with IIS/5 than with ICS, I saw two FTP errors with IIS/5 yesterday, and maybe 2,000 with ICS (many of those were the consequence of the FTP responses getting out of step).
