My VB6 code using Dart FTP connects with Passive = true and does stores and retrieves. Now, after successful login, both fail with a 10065 (remote host does not exist). Should I try passive=false or is this indicative of another problem related to server permission, etc.

Use the Trace method to create a log, then check the response the server gives to the PASV command. The first 4 numbers should be the same as the IP of the server. If they are not, then your clients firewall is not doing NAT properly. If the IP numbers are OK, check the 5th and 6th numbers to determine the port: port = (5th * 256) + 6th The firewall may be blocking inbound traffic to the server on that port.
