FTP problem, Internet Explorer, IIS 5.0

J

Jim Carlock

I'm having a problem establishing an FTP session with a
host which is running IIS 5.0. The problem ONLY exists
when using Internet Explorer or another browser and only
with one particular server. I can get regular FTP software
to connect, can get the DOS ftp.exe inside of XP to
connect. I can send remote commands via a DOS session:

ftp> quote HELP

But Internet Explorer does not connect to one particular
server (looks like I get a timeout message). Mozilla fails
to connect with such server as well.

The hosting company indicates that they can get IE to work
for them.

When using IE to establish connections with other servers,
the sessions connect properly with no problems. The other
servers are 21 hops away as with the server that I'm having
problems with. Tracing indicates the same amount of time
over the hops and the only difference are the user id's and
pw's used to establish the connection, as well as the final
four hops are slightly different.

To recap, I have tried the following:
1) Tracing the hops to see if there is anything problematic, it
looks okay.
2) Connecting via the XP DOS ftp.exe command, which
connects successfully without problems, and works fine.
3) Connecting via ftp programs, they all work fine.
4) Connecting via IE and Mozilla, neither one works with
one particular site.

Thanks for the reply Bernard.

These are the facts:
1) I am trying to get FTP to work through IE and Mozilla.
2) It works for everyplace except one particular site.
3) The following facts apply to all sites:
(a) All servers are running a SERV-U FTP server:
220 Serv-U FTP Server v5.2 for WinSock ready...
(b) All servers I am connecting to are running Win2K.
(c) All servers I'm trying to FTP to are running IIS 5.0.
4) I get IE to connect to 4 out of 5 servers. There is ONLY
one server that has a problem.
5) Tracert identifies no problem. Times are consistent
between all servers.
6) Ping identifies no problem. No packets are lost.
7) I have messed with the following IE settings:
(a) Use Passive FTP (Both modes work fine).
(b) Enable folder view for FTP sites. I think this used
to do something, but I can't figure out what it does now.
(c) Use HTTP 1.1 (this used to have to be checked but it
doesn't seem to be required any longer).
(d) Use HTTP 1.1 through proxy connections (this used
to have to be unchecked, to be able to delete items, but
there seems to be no way to delete items in IE any more).

When using IE to connect it immediately presents a cannot
find site/check DNS.

When using Mozilla or Firefox, they timeout after a minute or
longer, I've quit waiting today for them to timeout.

I am using IE/XP Pro (with all the latest updates, SP2).

I've reinstalled XP Pro and get the same results and IE seems
to be somewhat different than it used to be. I used to be able
to delete Files through FTP as needed as long as the "Use
HTTP 1.1 through proxy connections" was NOT checked.
Now, no matter what, I can't seem to get IE to delete any
files while connected through an FTP connection. The Delete
item on the menu is totally gone. It exists in Mozilla and Firefox
but I haven't figured out how to get those to work.

I can get FTP through various FTP software to connect and
work. All the alternative software works fine. I'm really puzzled
at the moment about why IE lost Delete from the menu.

Other people can connect just fine to the site, so it seems to
be a problem with XP Pro on my system.

The ONLY thing in the hosts file is:
127.0.0.1 localhost

Thanks much.

The FTP portion is Serv-U FTP. The backbone and the rest
is IIS 5 with FrontPage 2K Extensions. FrontPage works and
connects fine.

It seems to be isolated to my personal computer which has the
problems connecting (which is running XP SP2). IE connects
to some servers but doesn't connect to one particular server.

It's had me baffled for about a month now. And it's only an
Internet Explorer (or Browser) issue.

My first initial thoughts were some settings were messed up
with Internet Explorer or XP, so a reinstallation of XP was
done and the problem still exists.

The second thought to cross my mind was that perhaps there
is an issue involving the length of the username used to
connect with the server, but someone else connected fine
using their machine in another state. Right at the moment I
do not know which OS they used to connect.

So I'm back to it being a problem with my machine.

It does not seem to be an IIS issue. I've run out of ideas and
thoughts and I can get FTP software to connect and work.

I was out of ideas when I posted the request for help and I
only recently organized it in my own head. I am currently
leaning my thoughts that it is an XP issue rather than IIS.

Sorry, I'm confuse.
(a) All servers are running a SERV-U FTP server:

(b) All servers I am connecting to are running Win2K.
(c) All servers I'm trying to FTP to are running IIS 5.0.

so are you running Serv-U or IIS FTP ?

Yes, WS-FTP, as well as XP DOS FTP.exe, as well as a program
I've compiled myself all connect and retrieve files and place files
with 100% accuracy. It is ONLY with Internet Explorer and Mozilla
and only when connecting to one particular site out of four sites that
there is a problem. Very odd.

I don't know what the difference would be between a browser
and manually sending the commands. That's about the ONLY
clue I that comes to mind. Would you know if there is a max.
length to the line IE (or other browser) might work with, ie:

ftp://uuuiiiddd:p[email protected]

There is a very long UID and PASSWORD for the one that
has the problems.

I've been drawing blanks for a while. Would you know of a
tool that could be used to watch the data as it is being sent
out of the browser command line to the end server?

Bernard / Jim,

To let you know, I have exactly the same problem, and cannot find a solution
anywhere to this I am afraid.

I am running Windows XP Sp2 on the clients
Windows 2003 Server
IIS FTP using user isolation

Users can connect fine, can browse, but when they upload they can get about
anywhere between 0% and 60% of the way through an upload (independant of how
big the file size(s) is / are) and then it crashes IE. The FTP logs show
error 426 as the problem, even if previously uploaded files have been
successful.

DOS FTP and WS FTP both work without any problem.

I am using IE in passive mode (Active mode doesn't work!)

We too are using ADSL broadband!

Jamie

Sorry, I was away.
I have no more clues now :(

to know what data being sent between client and server, you can try network
sniffer.
you can try google.com
