I am uploading a 400MB file to the Website-panel file manager and get "HTTP Error 404.13 - Not Found". The log mentions verifying the configuration/system/.webServer/security/requestFiltering/requestslimits@maxAllowedContentLength setting in the applicationhost.config or webconfig file.

How do I make changes to this file on Windows 2008 r2?

applicationHost.config is located by default in %WINDIR%\System32\inetsrv\config\.

You can also use the Request Filtering feature from the IIS Manager. For more information on configuring Request Filtering see this configuration reference
