  7. On the Server Roles dialog box select, Web Server (IIS). If you are prompted to add additional features, click Add Features and then click Next.

  8. On the Role Services dialog box, expand the Application Development node and select ASP.NET 3.5. If you are prompted to add additional features, click Add Features.

  9. Repeat step 8 to select ASP.NET 4.5 and then click Next.

  10. Leave all other default role services selected.

  11. On the Confirmation dialog box, click Install. Proceed through the Add Roles and Features Wizard.

For more information on installing and configuring IIS and ASP.NET Modules on Server 2012 R2, see the Microsoft website: http://technet.microsoft.com/en-us/library/hh831475.aspx.

To enable ASP.NET extensions:

  1. On the web server, open the Windows Control Panel.

  2. Click Administrative Tools.

  3. Double-click Internet Information Services (IIS) Manager.

  4. In the left pane, click the local computer name.

  5. Double-click ISAPI and CGI Restrictions.

  6. In the list of ISAPI and CGI Restrictions, find the entry for ASP.NET 4.0.x (where x is the current release).

    Is this restriction allowed?

    • If yes, you have finished this procedure.

    • If no, right-click on ASP.NET 4.0.x and then click Allow.

    Note: If you do not see ASP.NET 4.0.x in the list, then either you do not have the 4.0 Framework installed, or you do not have ASP.NET 4.0 extensions installed. To install the extensions, run aspnet_regiis.exe with the -i option from the 4.0 Framework directory. By default, this is located at C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319. Then enable the extension.
