I want to know if i can install windows server 2008 "full installation" and put the Server Core default startup and make the server manager is just Secondary option. is that possible? , and how can do it? thanks for every one
In Windows Server 2008 and 2008 R2, you can not switch between Core and full server editions. The purpose of core is to limit the files installed and services running. A reinstall is required to change them.
You can however, install Server Core edition and use Server Manager from another server to do most management tasks.
