We have windows 2003 sp2 with iis 6 and when ever a large file download is
attempted via http the following error happens.

"Connection_Dropped DefaultAppPool" found in the httperr.log no event in the
event log and the browser shows:

The connection was reset
The connection to the server was reset while the page was loading.

The file is 92 megs. A file of 32megs downloads just fine.

My download of 272MB from IIS6 and WS03SP2 downloads just fine.

Connection_Dropped means exactly what it says. Perhaps something in
the network between your browser and server is throttling connection
time.

I have already checked with the networking guys. There is not QOS and the
port setting and the nics are configured correctly. The issue is that as soon
as I hit the 32 meg file.

http://website.com/file it starts to download till done fine. When I try the
92 meg
file
http://website.com/largerfile it fails withing about 5 seconds.

I have not found any good information to help me point to a possible
solution. Any help apprieciated.

Since I have no problems downloading 272MB from IIS6 and WS03SP2, your
issue looks to be either:
1. The person who deployed and configured the WS03SP2 server made some
configuration change that you'll have to figure out
2. Your download is handled by a custom ISAPI DLL which has bugs
3. The networking between the client and server is dropping the
connection within 5 seconds

Thanks for the suggestions.

After looking deeper into the IIS config I noticed we had ASP.NET 1.x and
ASP.NET 2.x both installed and was using 1.x. I changed it to 2.x and our
issue went away.
