Re: Bug with W2K3, SP1, Windows Firewall and FTP

From the Windows Firewall log, it looks like that the Firewall closes the
port 21 connection for some reasons. The client then gets the connection
disconnected by remote host/service not available, and since the server did
not get a proper response from the client, it is still waiting for the next
command (that's why the session is still going) until the session times out.
So the real question is why is the Windows Firewall doing this?

Oh, I also tested it from the server itself. Since the Firewall is not
involved in this case, everything went fine. Any thought on this Windows
Firewall behavior?

Well, even with the refresh button. it's only as 'real' as you thought.
it will only 'clear' from the list when the tcp connection no longer
appear when you do 'netstat -an' at command prompt.
that's what I have tested in the past.

here is a refresh button. I could see the connection time updated after
I clicked the button. BTW, the client I used was the Microsoft FTP.exe.

As for the FTP MMC connection status, I believe it is not refresh
realtime. so it may take someting to reflect even after the client has
disconnected.

You mean running FTP on the IIS/FTP server? Hmmm...I'll try that and
let you know the outcome.

I'm encountering a bad behavior with Windows Firewall on too. With
the Windows Firewall on, the FTP sessions (using the command line FTP
on the client) would be disconnected (the message says something
about connection disconnect by server) in about less than 1 minute,
but the IIS manager would still show the session is active. If the
Windows Firewall is off, everything is well.

Hello people,

I don't know if this is a documented bug or if the information is
wide
spread, but since we spend about two days tracking this down, I
think it
makes sense to share this information with whoever is interested in
it.

This is the setup where this will occur:
- Windows 2003 server with SP1
- Windows firewall turned on
- IIS on the same machine
- FTP within that IIS

Now, add a welcome message to the ftp. As soon as this welcome
message
contains a <return>, your browser will hang when you navigate to the
ftp-site. It does not actually hang, but returns an error much later
and your
ftp-site is not accessible.

Remove all returns from the welcome message, and the ftp-server
works just
fine...

Regards,

Benoit Somers.
