Connection reset by peer errors

[dni...@gmail.com]

I'm running Windows Server 2003 Standard Edition SP2. Around the time
I applied the SP2 update, users of my website who needed to download
large-ish (4MB - 12MB) files consistently started getting "Posix
error, connection reset by peer" errors.

Did something change in the SP2 update that would effect this?

Regardless, does anyone have suggestions on what to do to fix it?

Thx

Thanks Coraleigh, that definitely looks promising. I'll go ahead and
apply the fix that's listed in that KB article, and pray for the best!

Much appreciated, thanks again.

Unfortunately, it looks like that MS patch didn't fix the problem -
I'm still getting connection reset errors, regardless of browser used,
Mac or PC.

Any other thoughts?

Thanks...

Do you have any related Event ids in your event log?
Did you try all the Workarounds in the article as well?
Are you using ISA server?
Are you experiencing any other networking type issues? Any internal?

Nothing specific I can see. I *do* see a ton (2 per second!) of
System events from MSFTPSVC, failed login attempts due to bad password
or username. Seems like someone is trying to break in. Could that be
the problem? How do I block that?

> Did you try all the Workarounds in the article as well?

Yes - I applied the Resolution patch, and then also did Step 3 (Method
2, at the Registry level) and Step 4. I didn't do step 1 (not running
ISA server), and I couldn't find any new network drivers for Step 2.

> Are you using ISA server?

Nope.

No, everything else seems to be fine...

Thanks,
Dan

If your MSFTPSVC is an id 100 warning then it is due to people trying to log
into your system via FTP and having incorrect username or passwords. If you
do not use or need the FTP service you should uninstall it (via Add/Remove
programs-> Windows Components->Application Server-> IIS->FTP), or at least
disable the service. However, you said that you have external users who
download files from your website, if they are doing this with FTP then you
obviously should not remove it. :-)

I will do more thinking on this tommorrow.. in the meantime does anyone else
have any ideas for dnigrin?

Yes, those are the errors, but no, I can't turn the service off, as I
do need FTP running. I've not yet tested to see if the connection
reset errors occur with FTP (I will) - so far, all the errors have
been with *web* (HTTP) downloads.

One last thing I should mention - although I *think* that the errors
starting at the same time of the SP2 upgrade, I'm not positive about
that. Could some other automated MS update (I allow them to be
applied automatically) be the culprit? It's definitely something new
within the last month or two though...

Thanks for all your help thus far Coraleigh!

Small bit of followup - FTP downloads work fine; it's just HTTP
downloads which are stalling and having the connections reset.

Thanks in advance...

Ahhh..so perhaps we should look closer at your iis website config.

Take a look at your IIS Connection Timeout setting...

Thanks Coraleigh - I'll give those a look, though honestly I'm not
optimistic - I haven't touched those IIS settings in a long time, and
I didn't have the problem before. So unless one of the recent MS
updates changed something there on there own...

I doublechecked those settings, and they're all set at the defaults.
Also, the behavior when trying to download a file is that the download
starts, and is proceeding at a normal clip, when all of a sudden it
fails when the connection is reset. So it certainly doesn't seem as
though the connection is idle for a while, and then fails...

Ugh... I wish I could solve this!

Darn this is a tough one!

What is the file version of your \windows\system32\http.sys file on your iis
server?
You could run a sfc /scannow http://support.microsoft.com/kb/310747 to
verify that your system files are all the correct version, and fix any that
arent. Make sure you have a good backup of course before running this.

Also, you should try posting your issue to the
microsoft.public.inetserver.iis group site as they will be more
knowledgeable with iis specifically.
