Call IsSecurityEnabled to determine whether the MTS data module is currently protected by MTS or COM+ security services. MTS or COM+ security is enabled unless the object is running in the client's process. This can happen if an administrator configures the MTS data module to run in the client's process space (for example, an MTS Library package), or if the client application is in the same MTS package as the MTS data module.
