Can't connect to FTP sites

Question

This started happening when I installed Windows 7. I've tried with Filezilla and with the FireFTP Firefox plugin, and I could never connect. Filezilla gave the error message "ECONNREFUSED - Connection refused by server". I tried disabling the Windows Firewall, but no luck. Any ideas on what might be causing this?

I just discovered that I can connect with web services like net2ftp, but not with FTP clients.

Solution

Check whether

netstat -na

show you some SYN in line with IP of FTP site. Try to disable all port blocking on router (try to reset settings if you may to restore them after that)
Try to use ftp cmd command and print here all your interaction with the command.
I guess that this already not relevant, because it was 5 mounth ago, so why this question still open?

Are you behind a proxy server of some sort?

No, though I do have a router if it matters. It worked with Windows XP though.

Times out? That most likely means your isp is blocking the port or something else is.

Well, I was thinking it had something to do with the OS, since before install Win7 it worked.

Thank you for answering, but for some reason it now works. Thanks anyway.

After some time of not using FTP, I've found that for some mysterious reason it now works. Thanks anyway for bothering to answer this old question.
