7.0 - Chats not routing to agents - CCMWa logs indicate continuous crashes

PROBLEM

Chats are not routing to agents, and when you check the CCMWa log file you see constant errors. 

SYMPTOMS

In the CCMWa log file you will see errors like the following:

Error     16/10/2013 12:24:06 PM   Unhandled Application Exception found!
Error     16/10/2013 12:24:06 PM   ****************The exception before error reporting kicks in is: System.SystemException: Cannot create or update the database @. Please ensure that you are running SQL 2008 or higher and the database server is available. Connect via SQL Management studio to verify and then try this operation again. ---> System.Data.ProviderIncompatibleException: An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct. ---> System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) ---> System.ComponentModel.Win32Exception: The system cannot find the file specified 

CAUSE

The CCMWa uses a separate connection string in the Windows registry.  If this string is not created properly, or incorrect the CCMWa cannot connect properly to SQL. 

RESOLUTION

Ensure that the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\prairieFyre Software Inc\CCM\Enterprise\MCCConnectionString key is present and pointed to the correct instance of SQL.
