I'm trying to upload a file that is 107 mb to a test site that is running on IIS7. I changed the page code to not validate file size, but it still stops at around 7.5 mb. I've set the web.config to <httpRuntime maxRequestLength="2097151" requestLengthDiskThreshold="100"/> which is the largest number I could put in.
I tried it on my test box, which is Vista IIS 7 and got a different error message that I was probably hitting the file upload limit of IIS7 and to change the value in the applicationHost.config file. That might be what is happening on the real site, but the server administrator said there is no such setting in WS 2008 as the message box suggests.
I don't have the problem on your site with the demo large file upload page.
What else can I check?
Thanks
