Simple TCP/IP Services are really a collection of command line utilities. This collection includes the 'quote of the day' protocol, the daytime protocol, character generator (chargen), echo protocol, and discard protocol. These are just ports that are opened up on your Windows computer to perform specific testing or diagnostic functions. Therefore, these features should be configured correctly. Some programs and features included with Windows, such as Internet Information Services, must be turned on before you can use them. Certain other features are turned on by default, but you can turn them off if you don t use them. To turn a feature off in earlier versions of Windows, you had to uninstall it completely from your computer. In this version of Windows, the features remain stored on your hard disk so you can turn them back on if you want to. Turning off a feature does not uninstall the feature, and it does not reduce the amount of hard disk space used by Windows features. To turn Windows features on or off, follow these steps: * Click the Start button Picture of the Start button, click Control Panel, click Programs, and then click Turn Windows features on or off.
