    Hi Team,

    Could you please help me in resolving the error

    150 Opening ASCII mode data connection for file list.
    425 Can't open data connection.

    We are using IIS 6.0 for FTP ing the files , suddenly this stopped working only from a particualar computer in the network.We tried to FTP from different machines and everywhere it works but not just on one system which earlier worked perfectly (stopped working from 4 days)

    Tried to FTP from IE and it is working perfectly but just fails with command prompt as client.

    Firewall rules are open , Antivirus is also checked ..and they are good and nothing has been changed in the recent times.

    Please suggest if anything else need to be checked

    Thanks in advance..

    Hi Kiran,

    Hope you can spare some time learning what is FTP,

    http://en.wikipedia.org/wiki/File_Transfer_Protocol

    IE usually uses passive mode, while the command line utility (ftp command) always uses active mode.

    So the issue above can be a typical FTP active mode failure, which you still need to review firewall settings. Just this time you need to tune the firewall to work for active mode, not the same as passive mode.
