To manage, modify, or edit IIS configuration, you’ll need to use the IIS Manager on a different server/computer, and remotely connect to the IIS instance on Server Core. I originally had to figure this out so I could modify the “WsusPool” Application Pool on IIS on a Windows Server Core install that was hosting a WSUS Server to increase the Private Memory Maximum setting. So you have a Windows Server 2019 running Server Core with no GUI installed, and you have installed and are using the IIS (Internet Information Services) role and would like to manage or modify IIS configuration.īecause Windows Server Core doesn’t have a full GUI, you cannot install or use the Internet Information Services (IIS) Manager on this server.
