Can you try using passive mode?

I am on a Windows XP computer and the server that I am connecting to is Microsoft-IIS/6.0.

Hi,

I am suddenly having a problem connecting to a server via FTP. Strangely, all SFTP connections work fine, and most other FTP connections work as well. The error that I receive is:

Timeout detected.
Could not retrieve directory listing
Opening ASCII mode data connection.
Error listing directory '/'.

Prior to two days ago, I've been able to access this server for months, without a problem. And others are also able to access it. I've posted the logfile below.

Thanks in advance for your help!
