FIX: A CPI-C application may fail with a 0xc0000008 (invalid HANDLE) exception in a Host Integration Server 2010 environment

SYMPTOMS
You have an application that uses the Common Programming Interface for Communications (CPI-C) programming interface in a Microsoft Host Integration Server 2010 environment. When you run the application, you may receive an exception message that resembles the following:
