Alfresco Community 5.0 unable to upload files >5mb in size within share

So, I have Alfresco 5 running on Windows Server 2012 R2 with IIS 8.5 and I am not able to upload documents that are larger than 5mb in size. Files smaller are uploading as expected.

Upon uploading a document >5mb in size an errors on the share site will pop up either being a 404 or 502. Nothing is being notated within the log files. Any ideas? I'm assuming it has to be a setting restricting file size limit, but I am unsure.
