Adding Service-Related Values to the Ndi Key
If a component has an associated service (device driver), the add-registry-section referenced by the DDInstall section for that component must add a Service value to the Ndi key. The Service value is a REG_SZ value that specifies the primary service associated with the component. The Service value must match the ServiceName parameter of the AddService directive that references the service-install-section for the primary service. For more information, see INF DDInstall.Services Section.
If a component has one or more associated services, the add-registry-section referenced by the DDInstall section for that component must add a CoServices value to the Ndi key. The CoServices value is a MULTI_SZ value that specifies all the services that the component installs, including the primary service specified by the Service value. The CoServices value is required for all NetTrans, NetClient, and NetService components.
NoteNetClient components are deprecated in Windows 8.1, Windows Server 2012 R2, and later.
NoteNet components (adapters) should not have a CoServices value, because only one service can be associated with an adapter.
Except for shutting down services, all service-related actions are performed on the CoServices in the order that they are listed. For example, services are started in the order that they are listed. Services are stopped, however, in reverse order. Service-related actions for a component are performed on a service only if that service is listed in CoServices.
