Symptoms
When using the Distributed Component Object Model (DCOM) ConfigurationUtility (Dcomcnfg.exe), only one class for each ActiveX server appears inthe list of applications. This occurs even though an ActiveX server maycontain several classes, each of which is functioning correctly.
Resolution
DCOM provides server level security. All objects within a server share thesame security settings. Therefore, Dcomcnfg.exe only lists the first object(class) for each ActiveX server registered.
