iis ftp: for sbs2003/iis 6.0
had a virtual ftp site working with required user logon, anonymous not
allowd.then something happened somewhere somehow, and can not connect to
site. no errors in the ftp log but the could not bind instance 115 error
showed up in the system log, so i stopd and restarted site, there's no more
could not bind 115 errors, in the sys log but still can't access the site.
my firewall still has the same port 21 firewall config as before. i can
access the ftp site on the sbs machine only, can't access on my lan or
external thru the web.
any suggestions?

1) The binding error, could be due to port conflict, make sure no other
program is binidng on the site ip/port.

2) Temporary disable the firewall.... if still the same maybe at router
level blocking? this should be networking related as it works locally.

i ran portqryv2, -local, it did not indicate anything other than ftp was
listening on 21
when i connect with ie, it just hangs, if i connect with command line ftp, i
get a 220 ms ftp service reply, and then it hangs for about
1 minute, never get a prompt for username, them disconnects, 'connection
closed by remote host'
i ran portqryv2 remote and got
TCP port 21 (ftp service): LISTENING
but same thing as command line, it just dropped it
so it seems like i am getting thru the router (and sbs internal firewall?)
so if i am getting thru, any thing else to check?
thanks

Ya. it looks like only the first part that it get through, then something in
between drop it.
if you ftp locally at the server works?
do you have a publishing rules in ISA (SBS) that allow ftp traffic?

and do you know what changed recently ? as it was working before.

i will have to look at the isa, its another thing that has been below my
radar
i didn't set up the server initially, but i have provisioned all the ports
on the router,
however since it worked once, i'm thinking that the isa setup was ok then,
and i certainly
haven't made any changes to it. the server automatically gets it updates
from ms, so maybe one
of those made some changes that affect the ftp
since the last time ftp worked, i have installed php and mysql, which i have
on the default port 3306,
i have had problems, posted before here, but never resolved with the site
timing out, when transferring
multiple folder layers using the explorer option under tools. timed out no
matter how long i set the timeout
limit.

on the local lan

again ftp.exe works only the sbs machine only, ftp.exe from any other
machine hangs
as described in the previous posts.
firewall is a comcast small business router that has nat built in and port
forwarding only
it is very basic, i have port 21 fwd to the sbs machine, exactly as it was
when ftp was previously working
as far as i can tell isa is not running on this machine, it is not in
programs and it is not present in
the administrative tools list

so FTP is working then?
can you open up the firewall or disable it first to see if this is ISA
problem?

if yes, then check the publishing rules again.

thanks bernard for sticking with this, this is quite a long thread!

ok, windows firewall is NOT running, when i checked it there was a message
it can't even start due to
'another service is running that might use nat component, ipnat.exe'

when i open the ftp connection to the site in ftp.exe at the command line i
get these 2 messages:
Connected to domainWithNoFtp.com. :-)
Connection closed by remote host.

there is no machine between the sbs machine and the router, the sbs machine
is the gateway for the local lan
it provides dhcp, dns for 2 company domains, exchange, etc,

i tried just changing the ftp port to 22, and that didn't do anything,
changed on port fwding and in iis

Ok. I didn't the ISA part was blur maybe due to the medication :(
do you have any machine on the same subnet together with the sbs machine
before your router?
if the port is forwarding correctly you would at least see the ftp login
prompt, since 21 is open.

also what about the sbs windows built-in firewall? off ?

Mmm... not much detail on ipnat.exe but it should be related to ISA :)
I'm still suspecting networking issue as ftp works fine locally.

Have you post the ipnat error to isa group?
