Solution 1

Huge uploads (i.e. anything larger than 4Mb) is a problem with the FileUpload control, as it tries to prevent them in case of DOS attacks.
It's not too difficult to fix, but there is a good discussion of the problem here: http://www.infoq.com/news/2008/01/handling-large-uploads[^]

Solution 3

<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1009715200"></requestLimits>
</requestFiltering>
</security>
<system.webServer>

this will allow to upload maximum size as much as you want.
