Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I get the error 421 error connection timed out.

I am already in passive mode, but still it's not able to execute certain FTP commands like LIST , NLST. What could be the cause?

I tried using both Filezilla and IIS-7.

This is most likely a firewall issue as passive FTP clients connect to a random high port number for data transfers (including listings). This connection will need to be allowed into the server. –  USD Matt Apr 5 '13 at 9:47
