Microsoft Windows Server Manager is a tool to view and manage server roles and make configuration changes. Server Manager allows administrators to manage local and remote servers without requiring physical access to the servers or enabling Remote Desktop Protocol connections. Microsoft introduced the feature in Windows Server 2008 to give administrators the ability to install, configure and manage server roles and features.Content Continues Below
In Windows Server 2012, Microsoft updated Server Manager to allow it to add features and change server roles over the network. Server Manager could now manage multiple servers simultaneously and by role. Microsoft also increased the number of servers Server Manager can administer to 100. The number of servers that an administrator can manage with a single Server Manager console varies depending on the amount of data requested from the managed servers, as well as network and hardware resources available to the machine running Server Manager.
Windows Server Manager is installed by default on all editions of Windows Server 2012 and Windows Server 2012 R2. The Server Manager console is included with Remote Server Administration Tools for Windows 8 and Windows 8.1. Server Manager cannot manage servers on a machine running a higher version of Windows.
