## Chapter 7 Summary

The functionality of services under Windows NT will be familiar to UNIX administrators. The most noticeable difference is in how each is managed in its specific environment.

By default, a small group of services is installed during the Windows NT installation process. More services can be installed, and, if required, additional administrative tools, and anything else the service depends on, can be installed along with it.

Windows NT services are managed through a graphical user interface (GUI), while UNIX daemons are managed through command-line utilities. Windows NT service priorities are typically preset. Alerting a service priority involves working in the registry.

If you want to migrate services from UNIX to Windows NT, you will find there are many equivalent services already available.

The conceptual similarities and differences of Windows NT Services and UNIX daemons are summarized in the following table.

Feature type | Windows NT | UNIX
Process providing specific network service | Services | Daemons
Information for system boot and process startup | Registry | Multiple Configuration Files
Alter a service logon user ID | Log On As | Su, SetUID, SetGID executable

The administrative similarities and differences of Windows NT and UNIX are summarized in the following table.

Admin tool role | Windows NT | UNIX
Start a service | Control Panel, Services, Net Start | Run executable
Stop a service | Control Panel, Services, Net Stop | Kill, killall
Pause/continue a service | Control Panel, Services, Net pause/continue | N/A
Monitor service status and resource usage | Task Manager, Performance Monitor | Ps, Top
