425 use port or pasv first Error in Windows Server 2003

You encounter this because The FTP server wants to know what port you want to use either use a port-mode or passive-mode data channel. You don’t need to bother about this because most clients set up this automatically and choose passive because it is latest and better. But if you want to send command to the server you need to use the 'quote' command. Type this one:

quote PASV

then it should all work now. If you want some help regarding to this one you just type

'remotehelp'. Note that all of those can be use with the 'quote' command.

Hope this helped.

425 use port or pasv first Error in Windows Server 2003

This problem normally triggers two errors:

“500 Illegal PORT command”
“425 Use PORT or PASV first”

This problem normally happens when you initiate the FTP process from the command line and not using an FTP client. If you use Windows’ FTP command or FTP.exe, it appears it can’t shift to passive mode even if you run the without quotes “literal pasv” command. This issue is like a bug and the server, actually, doesn’t accept this command.

If you want to do an FTP session from the command line, one user found a workaround by disabling Windows Firewall first. Next, run the following command in the FTP window:

dir

It will work though the without quotes “ls” command may still not work. After this, enable the Windows Firewall and the without quotes “dir” command should continue to work though “ls” will continue to fail. This is just a remedy if you want to use FTP from the command line.

If you don’t want to encounter the problem, use an FTP client for your FTP session as it can easily shift between active and passive modes. If you are using Microsoft Windows, try FileZilla Client for Windows. It supports Windows Vista, Windows 7, Windows 8.x, and Windows 10 both 32-bit and 64-bit. The latest version of FileZilla no longer supports Windows XP.

For FTP server needs, try FileZilla Server for Windows. It supports Windows Vista, Windows 7, Windows 8.x, and Windows 10 both 32-bit and 64-bit. Unfortunately, unlike FileZilla Client that supports other operating systems like macOS and Linux, FileZilla Server is designed for Microsoft Windows only.
