The other the Communicator Web Access web site application kept failing.  If the application was started, the moment someone tried to access the site the application was disabled by IIS.

The error that was generated was  "The identity of application pool, 'CWAApplicationPool' is invalid and error code 80070532"

The solution was very simple.  The service account did not have the password never expires option set.  All I did was set this AD account option, and the application pool stopped being disabled.
