FTP PORT command binds to localhost?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

Does anyone know why FTP.EXE in the windows command prompt is binding to
127.0.0.1 when issuing a PORT command on a remote FTP server on the Internet?
the FTP client doesn't support passive transfers so I need active FTP to
work. I can get it to work by using "ftp -a ftp.ftpserver.com" but I'd really
want to know why I suddenly need the "-a" switch.

When using my FTP client in Total Commander I can se in the log that it's
binding to my actual IP address and everything works fine...

Example1 using FTP.EXE without the -a switch:

"D:\Downloads>ftp -d ftp.sunet.se
Connected to ftp.sunet.se.
220 Welcome to ftp.sunet.se
User (ftp.sunet.se:(none)):
---> USER
331 Any password will work
Password:
---> PASS
230 Any password will work
ftp> ls
---> PORT 127,0,0,1,5,21
200 PORT command successful
---> NLST
150 Connecting to port 16716"

....and then nothing happens!

Example 2 using the FTP.EXE with the "-a" switch:

"D:\Downloads>ftp -d -a ftp.sunet.se
Connected to ftp.sunet.se.
220 Welcome to ftp.sunet.se
User (ftp.sunet.se:(none)):
---> USER
331 Any password will work
Password:
---> PASS
230 Any password will work
ftp> ls
---> PORT 0,0,0,0,5,207
200 PORT command successful
---> NLST
150 Connecting to port 16722
bin
dev
etc
lib
ls-lR
ls-lR.gz
pub
usr
226 8 matches total
ftp: 47 bytes received in 0,00Seconds 47000,00Kbytes/sec.
ftp>"

...this one works but it seems to bind to IP 0.0.0.0 .

Example 3 using TotalCommander FTP client:

"Connect to: (2006-05-10 19:23:39)
hostname=ftp.sunet.se
username=anonymous
startdir=
ftp.sunet.se=194.71.11.70
220 Welcome to ftp.sunet.se
USER anonymous
331 Any password will work

Binding to my correct LAN IP address.

Is there any recently released windows security patch that causes this
behaviour of the FTP.EXE client ?

Thanks in advance for any input what so ever.
