There are endless software tools and utilities out there to help you in managing your network. Here are some of the best free ones. They can help you with deploying, maintaining, troubleshooting, and upgrading Window Servers, your domain, and aid with other miscellaneous network tasks.
Best Practices Analyzer
Microsoft provides the Best Practices Analyzer tool right inside Windows Server, starting with Windows Server 2008 R2, available on each role's home page in the Server Manager console. It scans and analyzes key settings of the server roles and reports compliance of them compared to the best practices standards. This can help you identify potential issues that may affect security and performance.It scans for a variety of rules, including those relating to predeployment, security, performance, and configuration. Statuses shown in the results include compliant, noncompliant, and warning.
Starting with Windows Server 2008, there's a Server Core installation option. It's great if you want a minimal installation, but it only gives you the Command Prompt for the interface. However, there are tools that give you a GUI on the Core editions of Windows Server. You can setup and configure most features via the GUI rather than being forced to use text commands.
