Re: Connection Aborted Message on IIS6 FTP

Netstat -s output give you such a high number or R A E ?
Received Address Errors = 1220449

if yes, it look like the interface itself is having issue.
I can't find much info on this error, so you may need to ping your network
admin and see if able to dig out more via sniffing the network packet.

you mentioned sometime no ftp connections can be made at all, hence i
replied that maybe network is giving problem. but if other protocol
connection is working during the same time, then yes network part is less
obvious.
still in between proxy/firewall/router acl/etc might prevent the connection
of ftp as well. or bad network card, cable, switches port, etc.....

You also mentioned that this only happen after sp2.
so is it possible to roll back sp2 and test further.

you need to isolate the possible factor starting by
- do you have the same problem if ftp'ing locally at the machine
- via same subnet? no firewall, no proxy
- via remote network ?

also anything weird from sniffed packet? check with your network admin.

Can you post the output of ftp.exe ?
Generic 426 is tough to troubleshoot.... if you dig out many posts have

no way with this.

Here is what I see...
ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
ftp: get :Connection reset by peer



In my recent experience w2k3 x64 ftp in cluster mode, the problem
randomly
occurred.
And nothing much from ftp or windows event log part, so we do a
sniffing...
all we see is connection error related, but then link is up all the time
and
accessible via other protocol, http, rpc, netbios, etc. it just ftp that
dropping random connections from time to time.

I am not running this in a cluster and am not using the x64 version.
However, like in your situation. every other protocol seems to respond
fine.


then we end up upgrade all network nic firmware + driver. and disable
chimney option via netsh on that interface and touch wood so far till now
it
is not happening again.

We have updated to the latest NIC driver. I am unsure of the NIC
firmware,
I will look into that. Also, the chimney option was disabled via the
registry in between one of the times the problem was occuring, and it did
not
fix the issue (and yes, it was rebooted afterwards).


take note that ur cases is different where zero ftp connections can be
made,
where as my case only few random connections.

It will make the initial connection in some cases (not all), but once you
try to navigate the issue stops the user cold.


sounds like your network go more problems than you think :)

This is not a network issue. This problem also occurs from the machine
itself when it occurs, so the network is ruled out. Also, this problem
never
occured until SP2 and the patches listed in the first message were
applied.

Also, I was just checking the system a few minutes ago and noticed that
the
response time is painfully slow. I anticipate that the issue will happen
again soon. In an attempt to do some troubleshooting, I ran a
"netstat -s"
command and found the following. Perhaps it is related to the problem
we're
seeing?
