Failure to download files larger than 16 Kb

Im using Winscp 4.3.3 in a server windows 2008 64 bits for ftp transactions

Everythig is ok, but when I download a file larger than 16 kb ( scripting or drag & drop ) it fails.
I get a timed out window.

I have the same winscp in a laptop windows 7 home edition and I download the same file correctly.


There is the error log for debug 1:

Have you tried another FTP client?

Yes I use FTP explorer and it download the files correctly. But I need winscp to use scripts.

Please post a log file from FTP explorer.

Sorry the tfp client is FileZilla
