Upgrading to Windows Server 2012 is blocked if the IIS Dynamic IP Restriction BETA module is installed

Symptoms

When you try to upgrade the operating system of a machine running Windows Server 2008 or Windows Server 2008 R2 to Windows Server 2012, the upgrade is blocked.

NOTE: This problem does not occur if the Dynamic IP Restriction module Beta 1 is installed on a Windows Server 2008 server that is then upgraded to Windows Server 2012.
