A. XP includes a built-in FTP service component that lets FTP clients connect to the machine and read or write files; however, this service doesn't install by default. To install the FTP service, perform the following steps:

  1. Start the Control Panel Add/Remove Programs applet (go to Start, Control Panel, then click Add/Remove Programs).
  2. Select Add/Remove Windows Components.
  3. Select Internet Information Services (IIS), then click Details.
  4. Select the File Transfer Protocol (FTP) Service check box, then click OK.
  5. Click OK to close all dialog boxes.

You can use the Microsoft Management Console (MMC) Internet Information Services snap-in to configure the FTP service (go to Start, Programs, Administrative Tools, then click Internet Information Services). After the snap-in starts, expand the computer name, then expand FTP Sites. A Default FTP Site will have been added. Right-click Default FTP Site, then select Properties from the displayed context menu to set options such as Home Directory, accounts, and anonymous access. To stop the FTP service, right-click the FTP site and select Stop from the context menu; likewise, select Start from the context menu to restart the service.
