IIS FTP Configuration - Failed to retrieve directory listing error in FTP Filezilla Client
After I configured the FTP site in IIS on Windows Server 2003 and added permission to a new FTP user on my FTP directory I ran into the following problem with my FTP Filezilla Client when trying to establish a connection to FTP Server. Output error: Failed to retrieve directory listing. In my case Filezilla Client normally established a connection but the client did not want to list my directories. After I checked all options in IIS I thought of seeing what is enabled in Windows Firewall. There I found a setting that solved my problem:
In Control Panel -> Windows Firewall -> Advanced tab click settings and check FTP Server to enable access.
That was it! My FTP connection then worked as expected.
