I'm trying to upload a WMV file through file manager, it's about 70MB, but whenever uploading to around 75%, the site refresh itself, and then up to 75%, it throws me error saying "the connection has been reset" (Google Chrome), here is my web.config setting:

<httpRuntime useFullyQualifiedRedirectUrl="false" maxRequestLength="102400" requestLengthDiskThreshold="8192" executionTimeout="600" requestValidationMode="2.0" />

<system.webServer>
      <security>
        <requestFiltering>
          <requestLimits maxAllowedContentLength="300000000" />
        </requestFiltering>
        <!-- Enable IIS Windows authentication for the login page -->
        <authentication>
          <windowsAuthentication enabled="true" />
          <anonymousAuthentication enabled="false" />
        </authentication>
      </security>
    </system.webServer>

Any idea I can get this working?

Cheers

I would strongly suggest you look at a custom uploader type module if you are going to regularly upload files of that size.  

The internal dnn uploader has never really been great at large files - look at a module that does flash or async upload maybe.
