IIS 7 WebResource.axd forbidden Windows Server 2008

New site deployment using IIS 7.5 on Windows Server 2008 R2.

HttpException: Because your server does not support reflection or you  set the attribute 'reflectionAlloweded="false"', You must specify a  non-autogenerated machine key in your web.config to compress  Webresource.axd

This issue is generated via the MbCompression library used to dynamically compress requests for Javascript files including the WebResources in asp.net 2.
My web.config does not have any configuration settings in the web.config for the Mbcompression library. The solution is very simple and was fixed by adding the Machinekey in the web.config in the section.

IIS 7.5 Windows Server 2008 R2: Access Denied Permissions

I'll just be short about this error. New to IIS 7.5 Windows Server 2008 R2 and have issues with permissions write access on folders that the application is using?

Write Access to folders will not cut it by simply giving permissions to IUSR or IIS_IUSRS group.

If the application pool is using “ApplicationPoolIdentity” this means that the application pool has its own user account.

You need to add the App Pool use to that folder and give it access.
