FTP directory security setup.

I'm trying to stop hackers from trying to accessing my ftp server.

I've tried to use the 'directory serurity' tab and "denied all" but the few
users I want to access my ftp site.
I've select "denied all but"  and entered the ip address of one system and
the domain of the other ex. "mydomain.com"  stopped the ftp server and
restarted it.
but
i still have hackers trying to login to my ftp server.

when does the "denied all "  take effect? after they login? , I thought it
would not respond to any request to login, unless it was in the exceptions
list.
did I not set it up correctly or is this how the "denied all" works?

TIA

system info 
nt 4.0 server  sp 6a
iis 4.0
applied half of the "harden nt server" suggestion ( i.e. stopping unneeded
services and removing shares, etc)

NT4 :) Denied all but... should block all except those you entered.
It's been a while I look at NT4. can you just test it with ip address,
forget about the domain name restriction first.

can you connect with that IP ? do you see other IP connecting?

the restriction took place when user connect before auth. you are seeing
otherwise ?

i'll try only the ip.
does the "deny all" restrict local ip such as 192.168.1.x? ,
if so I can test  with that ip address, dlocking it and allowing it.
otherwise I need to find someone outside my network.

but to answer the questions.

yes, I do see other ip address' trying to connect.
the log shows several attempts to enter a user name and password from ip
address' in NY, TX, poland, etc...

Yes, just denied all then allow your ip only.
I think it logged the connecting IP as well, even they are blocked.
you seeing 530 error right ?

Yes, you need to restart the ftp site as it cached the setting by default.

Next, regarding the connection reset by peer. how big is the file? could be
client or networking issue.
have you try a decent ftp client?

file size: the files are 1 to 2 gig.

I can download the files locally ( behind the linksys router)
might be that port 20 needs to be opened?

I'm thinking of looking at a few ftp pgms. but have not tried anything other
than

remote system:
xp home sp2
using start>run>cmd>ftp

local remote:
xp home sp2
using start>run>cmd>ftp

ftp server:
nt 4.0 sp6a iis 4.0

Thanks

I had the remote site tried to download a small file that worked.
when they tried to download a large file >900 meg  the get only a small part
of the file, I think thay said 35kb (not sure about the size) but it is the
same size for all files that they try to download.

is there a limit restriction in iis 4.0 or Xp that can be set?

TIA

More like networking issue to me, if it works internally.
What I can is that... if connection is slow or not stable between client and
server, these things happen. Best is to get network sniffer to look at
what's going on.
