Setting Up IIS 7.0 - Installing Web Servers

You can install a Web server by following these steps:

1.	Start the Server Manager by clicking the Server Manager icon on the Quick Launch toolbar or by clicking Start, Administrative Tools, Server Manager.
2.	In Server Manager, select the Roles node in the left pane and then, under Roles Summary, click Add Roles. This starts the Add Roles Wizard. If the wizard displays the Before You Begin page, read the Welcome page, and then click Next. You can avoid seeing the Welcome page the next time you start this wizard by selecting the Do Not Show Me This Page Again check box before clicking Next.
3.	On the Select Server Roles page, select the Web Server (IIS) role. You'll then see the Add Features Required For Web Server dialog box. This dialog box lists the features that are required to install a Web server. Click Add Required Features to close the dialog box and add the Windows Activation Service components to the Web server installation. Click Next twice to continue.
4.	On the Select Role Services page, Setup selects the core set of standard features by default. When selecting or clearing role services, keep the following in mind before you click Next to continue: If you select a role service with additional required features, you'll see a dialog box listing the additional required roles. After you review the required roles, click Add Required Role Services to accept the additions and close the dialog box. If you click Cancel instead, Setup will clear the feature you previously selected. If you try to remove a role service that is required based on a previous selection, you'll see a warning prompt about dependent services that Setup must also remove. In most cases, you'll want to click Cancel to preserve the previous selection. If you click Remove Dependent Role Services, Setup will also remove the previously selected dependent services, which could cause the Web server to not function as expected.
5.	Click Next. On the Confirm Installation Options page, click the Print, E-mail, Or Save This Information link to generate an installation report and display it in Windows Internet Explorer. You can then use standard Windows Internet Explorer features to print or save the report. After you've reviewed the installation options and saved them as necessary, click Install to begin the installation process.
6.	When Setup finishes installing the application server with the features you've selected, you'll see the Installation Results page. Review the installation details to ensure that all phases of the installation completed successfully. If any portion of the installation failed, note the reason for the failure and then use these troubleshooting techniques: Click the Print, E-mail, Or Save The Installation Report link to create or update the installation report and display it in Windows Internet Explorer. Scroll down to the bottom of the installation report in Windows Internet Explorer and then click Full Log (For Troubleshooting Only) to display the Server Manager log in Notepad. In Notepad, press Ctrl+F, type the current date in the appropriate format for your language settings, such as 2007-08-30, and then click Find Next. Notepad will then move through the log to the first Setup entry from the current date. Review the Server Manager entries for installation problems and take corrective actions as appropriate.
