* FUNCTION : CPCH_NetworkConnection::EnumerateInstances
*
* DESCRIPTION : Returns all the instances of this class.
*
* INPUTS : A pointer to the MethodContext for communication with WinMgmt.
* A long that contains the flags described in
* IWbemServices::CreateInstanceEnumAsync. Note that the following
* flags are handled by (and filtered out by) WinMgmt:
* WBEM_FLAG_DEEP
* WBEM_FLAG_SHALLOW
* WBEM_FLAG_RETURN_IMMEDIATELY
* WBEM_FLAG_FORWARD_ONLY
* WBEM_FLAG_BIDIRECTIONAL
*
* RETURNS : WBEM_S_NO_ERROR if successful
*
* COMMENTS : TO DO: All instances on the machine should be returned here.
* If there are no instances, return WBEM_S_NO_ERROR.
* It is not an error to have no instances.
