connecting to FTP service using IE (or other browser)

[Jim in Arizona]

I setup the new FTP 7.5 on my Server 2008 Standard.

I had to uninstall the other version first.

Using the following settings:
Allow SSL Connections
FTP Default Folder set to folder share on another server
\\server1\share\ftp
Anonymous Auth disbaled
Basic Auth enabled
Permissions set on \\server1\share\ftp folder to allow full permissions
for domain account called userftp

I set up a firewall rule to allow ftp and udp for port 21 inbound. I had to
do this to make it work.

It only works with command line connections. I can fire up a dos prompt and
use the command: ftp 123.123.123.123. I'll then get prompted for my
username, in which I put mydomain\userftp. Then prompted for my password and
everything just works fine. I then see the directory listing. I can then
download the file if I want.

Microsoft Windows XP [Version 5.1.2600]

C:\WINDOWS>ftp 123.123.123.123
Connected to 123.123.123.123

331 Password required for mydomain\userftp.
Password:

230 User logged in.
ftp> ls
200 PORT command successful.
125 Data connection already open; Transfer starting.

226 Transfer complete.

ftp> get Silverlight.2.0.exe
200 PORT command successful.

226 Transfer complete.

ftp> bye
221 Goodbye.

C:\WINDOWS>

So, it works just fine that way. Now comes Internet Explorer. I put in the
address bar ftp://123.123.123.123 and I'll get prompted for
username/password, which I put in. But then it just doesn't do anything.
After a while, it just times out by saying "Internet Explorer cannot display
the webpage". With firefox an error comes up that says "The server at
123.123.123.123 is taking too long to respond.. When I use Chrome, I do get
an error that says: "Error 2 (net: ERR_FAILED): Uknown error.".

Another note of interest. If I use the portqry command to check for port
status (I was doing this before I made the firewall rule opening up port 21
to figure out the first set of issues), I get this:

C:\WINDOWS>portqry -n 123.123.123.123 -e 21

Querying target system called:

123.123.123.123

Attempting to resolve IP address to a name...

IP address resolved to 123-123-123-123.dia.static.qwest.net

querying...

TCP port 21 (ftp service): LISTENING

Data returned from port:
220 Microsoft FTP Service

451 The parameter is incorrect.

C:\WINDOWS>

Note the last line where it says 451 The parameter is incorrect. That's odd.
I don't even know what that means. That error doesn't come up for any other
ports or locations I scan.

So, in the end, dos ftp works but web browsers do not.

Any ideas?

TIA,
Jim
