IIS6 upload files > 65MB failing

Hi,
i have a problem with IIS6 refusing to upload files larger than 65MB thru an
ISAPI extension web app, the same app runs on the dev machine with vista and
IIS7 no problems. i have tried that on more than one 2003 machine same
results, when the file is less than 65MB the w3wp.exe grows in memory as
much as the file size and its uploaded, but when its over that size IIS just
closes the connection and the client detects that 5 minutes later. the
website has its own app pool with the default settings.
any setting in registry maybe that limits the amount of memory app pool
use???
i have asp .net applications running on the same server and there is no
problems with them uploading files larger than 65MB, in fact they are only
limited by the web.config setting : where
x is upload limit in KB.
i have seen this problem searching on the net and not only with ISAPI but i
havent seen a solution for it.

Thanks

Please do not multi-post. Already answered elsewhere.

The problem is with your ISAPI Extension (or any frameworks like MFC
or ATL that it may be using).

Pure ISAPI Extension does not have such request limitation.
