I have come across a little information that I wanted to share with the DotNetNuke Community. I have been working tirelessly on allowing large uploads in the neighborhood of 2GB per file. I was able to do this easily with minimal effort once the learning curve had subdued. Keep in mind this is on a Windows 2003 IIS6 environment. The following are the steps needed:

1. First navigate to your dotnetnuke root folder (i.e. C:\wwwroot\dotnetnuke)
2. Open web.config in your favorite text editor (i.e. Notepad)
3. Find the following entry
4. <!-- allow large file uploads --> <httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength="2048000" requestLengthDiskThreshold="2048000" executionTimeout="1200" /> <httpCookies httpOnlyCookies="true" requireSSL="true" domain="" />
5. This is a snippet of my web.config note "maxRequestLength and requestLengthDiskThreshold" are in MB "exeutionTimeout" is in seconds.

Now for the second step:

1. Open Internet Information Services by navigating to Start>Administrative Tools>Internet Information Services (IIS) Manager
2. Right click on Computer Name (i.e. Localhost (local computer) ) and choose Properties
3. Put a check mark on Enable Direct Metabase Edit
4. Choose apply and close
5. Navigate to C:\Windows\system32\inetsrv
6. Find Metabase.xml
7. MAKE A COPY OF THIS FILE ( EDITING THIS FILE IS LIKE EDITING THE REGISTRY)
8. Open Metabase.xml with your favorite text editor
9. For uploads find the entry "AspMaxRequestEntityAllowed=" (THIS VALUE IS IN KB) I set the value to 52560000
10. Now for downloads find the entry "AspBufferingLimit=" (THIS VALUE IS IN KB) again I set the value to 52560000
11. Save the Metabase.xml

I recommend restarting your machine at this time and try your Uploads and Downloads. Works like a charm for me. I hope someone will find this useful I know it has taken me a week to get the correct information.

Thank you, Tony,

After a lot of trials and searching to allow for 1GB+ uploads to DNN, I saw your post and tried it.  IT WORKS! :-)

Thank you! Thank you!
