Large uploads fail in ASP with IIS

In IIS, the AspMaxRequestEntityAllowed property specifies the maximum number of bytes allowed in the entity body of an ASP request. This is set by default in the Metabase.XML (located in c:\Windows\System32\Inetsrv) to 204800 bytes (or 204KB). This may have been enough in 2003, but today it is pretty useless.

You need to change this in order to increase the limit. For example, 1073741824 would set the limit to 1GB. (You may wish to set it lower, but you get the idea).

You should use a plain text editor such as notepad.

If you want to edit the Metabase.XML file while your IIS server is running, you need to set a special property in your IIS Manager.

In IIS Manager, right-click the local computer, and then click Properties.

Select the Enable Direct Metabase Edit check box.

Enabling Direct Metabase Edit changes the EnableEditWhileRunning property from 0 (FALSE) to 1 (TRUE).

To edit the Metabase.XML without making any changes to your IIS server, stop the IIS server with the IISRESET /STOP command and make your changes, then use the IISRESET /START command to restart the server.
