I am having trouble uploading a file size over 4 MB. I've tried adding

<httpRuntime maxRequestLength="102400" executionTimeout="99999" />

to my Web.Config like many posts have suggested, but it just isn't working. Files under 4 MB work just fine, so I'm nearly certain I'm running into the 4 MB limit. Are there any settings in IIS that I might need to change?

Maximum value of maxRequestLength?

Max Request Length
