placed in the Location box. A Browse button will also appear, enabling a user to browse the location hierarchy for printers in other locations. This powerful feature simplifies printer administration and setup considerably. However, it obviously requires careful planning on the back end to ensure that all subnets are defined, and that a reasonable, hierarchical location naming convention has been applied consistently. More information about this feature is available in the online Help and Support Center.

Windows Server 2003 supports an additional set of functionality through the Internet Printing Protocol (IPP), which enables users to connect to printers and send print jobs over encapsulated Hypertext Transfer Protocol (HTTP). Internet printing also gives administrators the option to manage and configure printers using any variety of Internet browsers and platforms.

Internet printing is not installed or enabled by default in Windows Server 2003. You must install Internet Information Services (IIS), as discussed in 6. Internet printing is available for installation when you install IIS. To install Internet printing, perform the following steps: 1. Open Add/Remove Programs in Control Panel and click Add/Remove Windows Components. 2. Select Application Server and click Details. 3. Select Internet Information Services (IIS) and click Details. 4. Select Internet Printing. Once IIS and Internet printing are installed, you can disable or enable the feature using the IIS snap-in or console. Expand the server s node and click Web Service Extensions. In the details pane, select Internet Printing, and click Prohibit or Allow. Internet printing creates a Printers virtual directory under the Default Web site. This vir tual directory points to %Systemroot%\Web\Printers. The printer site is accessed using Microsoft Internet Explorer 4.01 and later by typing the address of the print server in the Address box followed by the Printers virtual directory name. For example, to access the Internet printing page for Server01, type http://Server01/printers/.

You can configure authentication and access security for Internet printing using the virtual directory s Properties dialog box.

You can connect to http://printserver/printers to view all printers on the print server. After locating the desired printer and clicking it, a Web page for that printer is displayed. As a shortcut, if you know the exact name of the printer to which you want to connect, type the address of the printer using the following format: http://printserver/printersharename/ Once the printer s Web page is displayed, you can connect to or manage the printer, assuming you have been allowed appropriate security permissions. When you click Connect on the printer s Web page, the server generates a .cab file that contains the appropriate printer driver files and downloads the .cab file to the client computer. The printer that is installed is displayed in the Printers folder on the client. The printer can then be used and managed from the Printers And Faxes folder like any other printer. Using a Web browser to manage printers has several advantages:

It allows you to administer printers from any computer running a Web browser, regardless of whether the computer is running Windows Server 2003 or has the correct printer drivers installed. It allows you to customize the interface. For example, you can create your own Web page containing a floor plan with the locations of the printers and the links to the printers. It provides a summary page listing the status of all printers on a print server. Internet printing can report real-time print device data, such as whether the print device is in power-saving mode, if the printer driver makes such information available. This information is not available from the Printers And Faxes window.

In this practice, you will configure printer pooling and configure a second logical printer to a single network-attached printer.
