Remote Server Administration Tools (RSAT) are a set of utilities that allow IT administrators to manage Windows Server roles and features from a remote computer. This means that instead of being physically present at the server, administrators can perform tasks like configuring settings, monitoring performance, and troubleshooting issues from their own devices. RSAT includes tools such as the Server Manager, Active Directory Users and Computers, and Group Policy Management. These tools help streamline server management, making it easier to maintain and secure networks, especially in environments with multiple servers or remote locations.
