The Services subkeys under the following registry path contain parametersfor the device drivers, file system drivers, and Win32 service drivers:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ServicesThe name of each Services subkey is the name of the service, which is alsothe root of the name of the file from which the service is loaded. Forexample, for the serial mouse, the service name and Services subkey name isSermouse. The file from which this is loaded is:SystemRoot\SYSTEM32\DRIVERS\SERMOUSE.SYS.All service names are defined under: HKEY_LOCAL_MACHINE\SOFTWARE.The names of the Windows NT built-in network services such as the Alerterand Browser services are defined under the Microsoft\WindowsNT\CurrentVersion subkey in the Software area of the Registry.Each Services key can have additional subkeys. Many services have a Linkagesubkey, which provides data for binding network components, as described in"Linkage Subkey Entries for Network Components," in the article "NetworkAdapter Cards Entries, PART 1." Many services also have a Parameters subkeythat contains entries defined by the service with values for configuringthe specific service.Values for Parameters subkeys and other service-specific entries aredescribed in these articles:Network Adapter Cards EntriesDevice Drivers EntriesNetwork Services EntriesThe following standard value entries appear for each Services subkey:ErrorControl REG_DWORD Error constantSpecifies the level of error control for the service as follows:Error Control MeaningLevel0x3 (Critical) Fail the attempted system startup. If the startup is not using the LastKnownGood control set, switch to LastKnownGood. If the startup attempt is using LastKnownGood, run a bug-check routine.0x2 (Severe) If the startup is not using the LastKnownGood control set, switch to LastKnownGood. If the startup attempt is using LastKnownGood, continue on in case of error.0x1 (Normal) If the driver fails to load or initialize, startup should proceed, but display a warning.0x0 (Ignore) If the driver fails to load or initialize, start up proceeds. No warning is displayed.Group REG_SZ Group nameSpecifies the name of the group of which the particular service is amember.Default: (null)DependOnGroup REG_MULTI_SZ Group nameSpecifies zero or more group names. If one or more groups is listed, atleast one service from the named group must be loaded before this serviceis loaded.Default: (empty)DependOnService REG_MULTI_SZ Service nameSpecifies zero or more Services subkey names. If a service is listed here,that named service must be loaded before this service is loaded.Default: (empty)ImagePath REG_DWORD Path and filenameSpecifies a path name. For adapters, this value is ignored.Default: For a driver: systemroot\SYSTEM32\DRIVERS\driverName.SYSFor a service: systemroot\SYSTEM32\serviceName.EXE(where driverName or serviceName is the same as the related Services subkeyname)ObjectName REG_DWORD Object nameSpecifies an object name. If Type specifies a WIN32 Service, this name isthe account name that the service will use to log on when the service runs.If Type specifies a Kernel driver or file system driver, this name is theWindows NT driver object name that the I/O Manager uses to load the devicedriver.Default: subkeyNameStart REG_DWORD Start constantSpecifies the starting values for the service as follows:START TYPE LOADER MEANING0x0 Kernel Represents a part of the(Boot) driver stack for the boot (startup) volume and must therefore be loaded by the Boot Loader.0x1 I/O Represents a driver to be loaded(System) subsystem at Kernel initialization.0x2 Service To be loaded or started(Auto load) Control automatically for all startups, Manager regardless of service type.0x3 Service Available, regardless of type,(Load on Control but will not be started untildemand) Manager the user starts it (for example, by using the Devices icon in Control Panel).0x4 Service NOT TO BE STARTED UNDER ANY(disabled) Control CONDITIONS. ManagerThe Start value is ignored for adapters. If Type is a Win32 Service value(as described below), the Start value must specify an Auto, Demand, orDisabled value.Tag REG_DWORDSpecifies a load order within a given group. The value of Tag specifies anumber that is unique within the group of which the service is a member.The related GroupName entry under the Control\GroupOrderList subkeyspecifies a list of tags, in load order.For example, the following services that are members of the Primary Diskgroup could have these values: Tag=4 for the Abiosdsk subkey, Tag=2 forAtdisk, Tag=1 for Cpqarray, and Tag=3 for Floppy. The value for PrimaryDisk under the GroupOrderList subkey will use these Tag values to specifythe defined order for loading these services. As another example, each SCSIminiport service has a unique Tag value that is used as an identifier inthe SCSI miniport value under the GroupOrderList subkey to define whichSCSI adapter to load first.Type REG_DWORD Type constantSpecifies the type of service as follows:Service Type Description0x1 A Kernel device driver.0x2 File system driver, which is also a Kernel device driver.0x4 A set of arguments for an adapter.0x10 A Win32 program that can be started by the Service Controller and that obeys the service control protocol. This type of Win32 service runs in a process by itself.0x20 A Win32 service that can share a process with other Win32 services.For example, when you start Windows NT, the Boot Loader scans the Registryfor drivers with a Start value of 0 (which indicates that these driversshould be loaded but not initialized before the Kernel) and a Type value of0x1 (which indicates a Kernel device driver such as a hard disk or otherlow-level hardware device driver). The drivers are then loaded into memoryin the order specified as the List value inCurrentControlSet\Control\ServiceGroupOrder.
