Cannot download large files on a W2K3 network.

We have a W2K3 SP2 Ent ED network of 40 PC with 15 running W98 and the others
WinXP SP2 and all machine have IE6. It makes no different which PC I use on
the network, any file larger than 75mb and larger will NOT download. IE6 ask
if you want to save or run the file, I click save and select the file
location at which point IE6 errors out "IE cannot download this file because
the connection to the server was reset". I've also notice that the temp file
is created, about 104K, than deleted.
I have serach everywhere and no one seem to have any ideas. There is no
firewall running on the server and I am logon as administrator with full
access to everything.

What are you downloading and from where?

Have you, by any chance, set your browser cache to 75Mb?

The file Encore Pro ver 1.5 full version @ software.respironics.com - this is
a medical data collection database which is compress to *.exe - The browser
cache are not touched. What ever the defaults are that's what set. I do not
have this problem in my home office. Only @the clients office. I failed to
mentional the SonicWALL appliance attached to the incoming Internet
connection however after taking to SonicWALL they assure me that it was not
the appliance causing the problem.

Has the client installed any of those silly "download accelerator" things?

Are there any messages in the client event logs on the XP machines from, for
example, antivirus programs moaning about the download file?

Are they using ISA server or any other kind of proxy on the Windows server,
or are they just using the sonicwall appliance?

Can you download other large files from other websites? What happens if you
try to grab, say a copy of Open Office?
(http://download.openoffice.org/index.html) That's a nice 90 Mb test file
right there.

Is the sonicwall appliance a caching internet appliance or just a firewall?
What happens if you attach one of your working computers from the home
office directly to the sonicwall appliance at the client office and try the
download again?

I know you mentioned Windows 2003 server, but if you don't have an internet
proxy installed on that and the gateway to the internet for users is
logically defined as ...

[client]--->[sonicwall appliance]-->[ISP]-->Internet

.... then the fault has to be somewhere on that diagram so we can probably
eliminate the windows 2003 server from the list.

If you can test a "known good" machine from your home office and it works ok
plugged into their network then the issue is probably with their
workstations.

Otherwise its either the sonicwall or perhaps the connection to the ISP.
While SonicWall assure you it isn't down to their product they can only
comment on how they *intend* it to behave - it or another component in the
internet connection (is there a router?) could be misconfigured or there
could be an unforseen issue between it and the ISP.

I'm always surprised at "professionals" who STILL have to be asked "Have you
checked (event viewer / syslog)".

No ISA, proxy, server and no such accelerators of any kind. The only
appliance is the SonicWALL. No messages of any kind showing up in the event
viewer (XP nor server). However here is an update to my recent attemp. On
the server only I installed FireFox Web browser. The browser also gave me
the same error however it provided a reason for the error that the browser
was not able to open the file that it create in the first place in the temp
folder. I check to see if a file was created and it was there but for some
reason it behavior was weir like if the file was read only. I checked all
settings and nothing was set to read only. So the browser create a file to
capture to but then it cannot keep the file open to add to the file. Does MS
know about this.

Any errors that firefox may have locally to itself and any errors that
Internet Explorer may have locally to itself are going to be unrelated,
given that they are totally different products from totally different
suppliers and built using totally different philosophies.

Observed behaviour in Firefox suggests that when you attempt to download a
large file it creates a zero length file and then attempts to add content
into it from the download stream, hence a failure to add to this file could
be nothing to do with the local PC, instead being a problem with the
download.

Robert I can't say enough about your help and suggestions. Thanks.
FYI - I am going to see if I can bypass the appliance all together. Hoping
that I can get a chance on the download. By the way it makes no plus or
minus on the file or file type just the size. It is also affecting XP SP2
Windows Update. I can't win.
