A FTP server i have recently configured using IIS 5 (W2K Server) is very spotty when connecting from the internet. Inside of my network the server works perfect from a browser or a command prompt. However, when attempting to connect from the internet, in a browser I recieve "FTP Folder error. The connection to the server was reset." When attempting to connect from a command prompt, I recieve "Connected to (server name). Connection closed by remote host". My firewall is configured properly to allow ftp traffic to the private address for the server and to one to one NAT the public address to the private address. However my ftp site is not accessable. What is really baffling me is that continuous retries from the browser will eventually allow access. The same with the command prompt. It doesn't work all the time, but it does work sometimes.
Please Help!!! I am stumped!
