Manually enable IIS and required components

ArcGIS Web Adaptor requires that IIS and specific IIS components be enabled on supported Windows operating systems. The setup will not proceed if IIS is not detected and specific IIS components are not enabled.

If you've already enabled IIS but are missing the required IIS components, the installation displays a message indicating that certain IIS components are missing. You have the option to allow the installation to automatically enable the required IIS components. However, depending on your organization's security policies, it may be necessary to manually enable the required IIS components as described below.

To enable IIS and the required components on Windows Server 2012/2012 R2, Windows Server 2016, and Windows Server 2019, complete the following steps:

1. Open Server Manager and click Manage > Add Roles and Features. Click Next.
2. Select Role-based or feature-based installation and click Next.
3. Select the appropriate server. The local server is selected by default. Click Next.
4. Enable Web Server (IIS) and click Next.
5. No additional features are necessary to install the Web Adaptor, so click Next.
6. On the Web Server Role (IIS) dialog box, click Next.
7. On the Select role services dialog box, verify that the web server components listed in the Required IIS components section are enabled. Click Next.
8. Verify that your settings are correct and click Install.
9. When the installation completes, click Close to exit the wizard.

To enable IIS and the required components on Windows 10 and Windows 8/8.1, complete the following steps:

1. Open Control Panel and click Programs and Features > Turn Windows features on or off.
2. Enable Internet Information Services.
3. Expand the Internet Information Services feature and verify that the web server components listed in the Required IIS components section are enabled.
4. Click OK.
