This issue is caused when the Default Web Site is removed from IIS and EV attempts to add a virtual directory.
Typically, this is done as a part of server hardening. All other prerequisites are installed and Deployment Scanner does not show any issues with IIS as it is installed on the server.
Recreate the Default Web Site under IIS to allow for the EV virtual directories to be created properly.
To recreate the Default Web Site in IIS with the standard configuration, including the default application pool and physical path, follow these steps:
1. Open IIS Manager by searching for IIS Manager in the Windows Start menu or by running inetmgr from the Run dialog.
2. Expand the server name in the left-hand Connections pane, right-click on the Sites node and select Add Website from the context menu.
3. Configure Website Details:
3.1. Site name: Default Web Site
3.2. Application pool: Select DefaultAppPool
3.3. Physical path: Set this to %SystemDrive%\inetpub\wwwroot. This typically resolves to C:\inetpub\wwwroot.
3.4. Binding: Leave the default settings for the binding (Type: http, IP address: All Unassigned, Port: 80).
3.5. Click OK.
4. The newly created Default Web Site should now appear under the Sites node in IIS Manager. Ensure it is started (indicated by a green play icon). If it is stopped, right-click and select Start.
