Before You Begin
Ensure that you have administrative user rights on the computer on which you plan to install IIS 7 or above. Note that by default, you do not have administrative user rights if you are logged on as a user other than as the built-in administrator, even if you were added to the local Administrators group on the computer (this is a new security feature in Windows Server 2008 called Local User Administrator).
Log on either to the built-in administrator account, or explicitly invoke applications as the built-in administrator by using the runas command-line tool.
Note: You can run runas /user:administrator cmd.exe so that every application you run from that command line will be elevated, eliminating the need to use the runas syntax from that command line.
If you are logged on to an account other than the built-in local administrator account, you may see the following security alert dialog box.

IIS is one of the Windows Server®
server roles. IIS can be installed through the graphical user interface (GUI) by using the new Server Manager interface after the Windows Server operating system is installed.
Server Manager provides a single dashboard to install or uninstall server roles and features. Server Manager also gives an overview of all currently installed roles and features. When IIS is chosen from the Server Manager, the basic components and services needed for IIS are automatically selected.
1. Click Start -> All Programs -> Administrative Tools -> Server Manager.

2. In the Server Manager window, scroll down to Roles Summary, and then click Add Roles. The Add Roles Wizard will start with a Before You Begin page. The wizard asks for verification of the following:
a. The administrator account has a strong password.
b. The network settings, such as IP addresses, are configured.
c. The latest security updates from Windows® Update are installed.
3. Select Web Server (IIS) on the Select Server Roles page. An introductory page will open with links for further information.
Note: When you use the Add Roles Wizard to install IIS, you get the default installation, which has a minimum set of role services. If you need additional IIS role services, such as Application Development or Health and Diagnostics, make sure to select the check boxes associated with those features in the Select Role Services page of the wizard.

4. Select the IIS services to be installed on the Select Role Services page. Add only the modules necessary. In this case, ASP.NET is selected, and a description of ASP.NET appears in the right pane. Once desired modules are added, click Next.

5. Add any required role services.

6. IIS is now installed with a default configuration for hosting ASP.NET on Windows Server. Click Close to complete the process.

7. Confirm that the Web server works by using http://localhost.

Note: Install only the absolutely necessary IIS services to minimize the IIS installation footprint. This also minimizes the attack surface, which is one of the benefits of IIS 7 and above.
Use a Script to Install IIS 7.5 on Windows Server 2008 R2
You can also use a script to install IIS 7.5. Note that if you use this script, you get the full IIS installation, which installs all available feature packages. If there are feature packages you do not need, you should edit the script to install only the packages you require. For more information, see Installing IIS 7.5 on Windows Server 2008 R2.
To install IIS 7.5 with a script, type the following at a command prompt:
