If you bought a new Windows server without a hosting control panel, IIS may not be installed by default. Therefore, we must install it first. How to do this?
1. Click Server Manager on the bottom left.
2. Then click Manage > Add Roles and Features.
3. You will be asked for some features to install. Select as follows:
Installation type: Role-based or feature-based installation.
Server selection: Select a server from the server pool.
Server roles: select IIS Web Server > Add Features
4. Next continues, then finally select Install.
5. Wait for a while, where the server is installing. Estimated about 1-3 minutes.
6. Done. Your IIS is now installed.
