BUG: Error Message When You Upload a Large File

When you upload a large file through the Resource Manager, you receive the following error message:

When you upload a file that is larger than the size that is specified in the Machine.config file, an error occurs on the server. Because the server refuses the request, the uploading browser reports that the submission page is not available and returns a "Page Cannot Be Displayed" error message.

Configure maxRequestlength in the Machine.config file for a larger size (in KB).

NOTE: Machine.config is typically located in <Windows_Root>\Microsoft.NET\Framework\<version_number>\Config.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.

By default, the maximum request size for uploading files is 4 MB. You do not receive a user friendly error message when you try to upload a file that is larger than the size that is configured in the Web.config file.
