Upload issue on IIS 6.0

Hi,

I have weird issue on windows 2003 (iis 6.0) with uploading documents
over 4MB. The application works with documents upto 4 MB, but anything
over 4 MB fails. I have modified entry
ASPMAXREQUESTENTITYALLOWED=1073741824 in metabase.xml, it should
support upto 1 GB. Its ASP application not ASP.NET.

Appreciate your help.

Thanks
SAI

Do you have SiteMinder isapi filter installed? This filter also has a
setting to limit the size of an upload. If you have it installed, you need
to remove it and completely uninstall it. Once you do this, test to see
if you can upload files larger than 4mb. If so, then it is a setting with
the Siteminder isapi filter. You can add the following key to the
registry to change the setting:

1. Go to HKEY_LOCAL_MACHINE/Software/Netegrity/Siteminder Web
Agent/Microsoft IIS
2. Add a DWORD value named MaxRequestAllowed and set it to desired size in
bytes.
Example, if you want to set it to 20 mb, the value would be 20000000.

Hope this helps!

Thank you,

Thanks for the response, I dont have SiteMinder ISAPI filter, and also
checked registry key, doesnt exists. This is a brand new installation
and just configured for web server. We used microsoft migration tool to
migrate the code from windows 2000 (IIS 5.0) to windows 2003 (IIS 6.0).

Thanks

I found the problem, IIS 6.0 is uploading the file to a network folder,
and as soon as I changed it to upload it local system it worked fine.
But the same setting worked fine IIS 5.0, it looks like IIS 6.0 is
having issue in uploading the file to network folder. Any thoughts?

Is there adequate free space on the network folder? Any connection/network
problems between the two servers?

There is enough space and also dont have any known connection/network
problems. After doing some analysis I found out that first 2 MB copies
faster and later it slows down and die at one point (and this point
varies, sometimes around 4 MB, sometimes around 6 MB). IIS 5.0 also
uploads to same network folder and there is no issue. It looks more of
IIS 6.0 or it may be the upload component (ASP Soft), but for me it
looks like IIS 6.0 is the issue as the same upload component works with
IIS 5.0

From my perspective, this looks more like an ASP Soft/ Windows Server 2003
app-compat issue because IIS does not have anything to do with "upload to a
network folder".

IIS simply receives uploaded data from the client, and hands the data to
your script. Your script runs on IIS and calls the ASP Soft component to
make a file copy to the network folder. Thus, IIS is not doing anything
related to your failing file copy because it is not copying anything.

I think that this may be one of the SMB performance issues in Windows Server
2003 fixed in SP1.

I agree with you, but it still beats me up, as the same ASP Soft is
working fine on windows 2000. SP1 is already installed on windows 2003
server. For now I am uploading to local path and moving to network
path, which works perfectly fine. Thanks for the feedback.
