Windows Server 2008 in part already allowed administrators to manage the network with Server Manager. However, that was all fairly rudimentary. For example, Server Manager in Windows Server 2008 could not install roles over the network, and the management of server roles was not very efficient. Windows Server 2012 is vastly improved. For example, in Windows Server 2012, you can install server roles and features over the network on other servers.
Microsoft has combined the wizards for installing server roles and features into a single wizard. This approach makes the process easier and faster because only a single install is necessary. Server Manager automatically groups installed server roles together with the appropriate servers. Server Manager lists management tools directly in the Tools menu, and you can even edit the Tools menu. To do this, open the Control Panel and look for 'System and Security->Administrative Tools'. Server Manager shows all of the links in this area in the Tools menu. At this point, you can add more links, remove links, and even create a folder structure.
To use Server Manager in Windows Server 2012 to connect to more servers, just click on Manage and then Add Servers . In the window, you can then search for servers, so you can manage them in your local Server Manager. In this way, you also create your own groups of servers, which you can combine in Server Manager. You can then view event messages for these groups. Note that you can only install server roles and features if you have previously connected to the appropriate server.
