You will begin the installation of IIS on Windows Server 2008 R2 using the Internet Information Services (IIS) Manager, located within the Administrative Services Console.
On the IIS Manager screen, under the "Customize This Server," click "Add roles" to open the "Add Roles Wizard."
On the first screen of the Add Roles Wizard click "Next"
On the "Select Server Roles" screen select the "Web Server (IIS)" role from the options in the window and click "Next."
On the Web Server (IIS) screen click "Next," again, which will bring you to the "Select Role Services" screen. Leave the default options as they are and click "Next."
Then, click "Install" on the "Confirm Installation Selections" screen.
This will trigger the Installation process. You will see the installation progress in the progress bar. Once the installation finishes, the "Installation Results" screen will appear and you will see a green-button checkmark indicating that the installation succeeded.
Click "Close," which will return you to the "Initial Configuration Tasks screen." There, beside "Roles," you will see the installed Web Server (IIS).
To manage the IIS, open the "Start" menu and run the IIS Manager.
Within the IIS Manager, open the file tree beneath your server name in the left pane. "Click Sites," then click on "Default Web Site."
