Are you looking to register ASP.NET with your IIS web server? This tutorial will guide you through the process step-by-step, ensuring that you can seamlessly integrate ASP.NET into your web server environment. Let’s get started!

Step 1: Install ASP.NET

To begin, make sure that you have ASP.NET installed on your machine. If not, head over to the official Microsoft website and download the latest version of ASP.NET. Once downloaded, follow the installation instructions provided by Microsoft.

Step 2: Open Internet Information Services (IIS)

Once you have installed ASP.NET, it’s time to open Internet Information Services (IIS) on your machine. You can do this by following these steps:

  1. Press the Windows key on your keyboard
  2. Type “Internet Information Services”
  3. Click on the “Internet Information Services (IIS) Manager” application

Step 3: Select Your Website

In the IIS Manager, navigate to the “Connections” pane on the left-hand side and expand it. You should see a list of websites hosted on your machine. Select the website where you want to register ASP.

Step 4: Open Handler Mappings

In the selected website’s pane, locate and open “Handler Mappings”. This option allows you to manage how various file types are processed by IIS.

Step 5: Add a Script Map

In the Handler Mappings section, click on “Add Script Map” from the Actions panel on the right-hand side. This will open a new window where you can configure the script map settings.

Step 6: Configure the Script Map

In the “Add Script Map” window, configure the following settings:

  • Request path: Enter the path for your ASP.NET application (e.g., *.aspx)
  • Executable: Browse and locate the ASP.NET ISAPI dll (e., C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll)
  • Name: Give a name to this script map (e., ASP.NET)

Step 7: Confirm and Apply Changes

Once you have configured the script map, click “OK” to confirm. The new script map should now appear in the Handler Mappings list.

Step 8: Test ASP.NET Registration

To ensure that ASP.NET is registered correctly with your IIS web server, it’s crucial to test your configuration. Open a web browser and navigate to a page within your website that uses ASP.NET functionality. If everything has been set up correctly, you should see the page rendered without any errors.


You have successfully registered ASP.NET with your IIS web server. Now you can start building powerful web applications using ASP.NET and take advantage of its extensive features and capabilities.

In conclusion, registering ASP.NET with your IIS web server is a relatively straightforward process when you follow these steps. By integrating ASP.NET into your web server environment, you unlock a world of possibilities for developing dynamic and interactive web applications.

Note: It’s important to keep your ASP.NET installation up to date to ensure compatibility with the latest features and security patches. Regularly check for updates on the official Microsoft website and apply them as necessary.
