Echoing what Chris said it is my experience that many Windows FTP
products are poorly written and several have caused my administrators (and my
users) much heartache. So much so in some cases that we have formally
stated they should not be used and will not be supported by our internal
resources. Filezilla is a good choice and is the application we
load on Windows systems for users that require it.
Are you running Wireshark on the client or the server?
If you can do both and compare them that may give you enough information to
determine the real cause of the problem.
Also, given your statement that it was working and now isn't,
you should obviously focus on the things that might have changed in your
environment. Was a piece of networking gear replaced? Were the
server or client updated with OS or security patches? That sort of
thing.

Sounds like active/passive FTP problem.
Windows FTP uses active mode by default.
Active mode can often have trouble working through
firewalls/routers.
When you have connected to the ftp site type the command
‘literal pasv’ which should switch the client into passive mode.
To make permanent default see here:

Better still use a decent ftp client like filezilla
http://filezilla-project.org/download.php
Also remember if your not using sftp or scp the traffic or the
password to the ftp site is not encrypted……

Subject: [Wireshark-users] FTP analysis
I have a ftp connection to a server and I am trying to analyze why even though
wireshark shows that the files are transferrred successfully Windows ftp does
not complete the transfer. How do I go about analyzing the problem ?
226 Transfer complete successfully.
but the windows ftp client does not save
the file. It hangs. So what was working a few days back is now hanging. What
type of analysis should I run ?
