Feature Administration gives you access to tools like the Failover Cluster Manager snap-in and the cluster.exe command-line tool for administering failover management. If you've installed Support Tools for Server 2000/2003 as ADMINPAK.MSI, you will find the tools included within Server Manager on Windows Server 2008 systems. You can add these tools to Vista or Windows 7 by searching for RSAT downloads from Microsoft and then installing them on your systems. After installing the tools, you will need to enable them through the Programs and Features | Turn Windows features on or off.
Note: The tools do not install on all editions of Windows Vista or Windows 7. For example, with Windows 7 you need to run Enterprise, Professional, or Ultimate edition.
Top free Microsoft server tools: SQL Server 2008 R2 Best Practices Analyzer
Microsoft's Best Practices Analyzer (BPA) for SQL is a real time-saver for IT admins and even DBAs. The tool scans your system, reporting back all configuration settings, complete with very clear markers as to which settings should be adjusted to align with SQL best practices as outlined by Microsoft. Prior to BPA, tuning SQL settings to achieve the ideal configuration was strictly a manual affair. But with BPA, admins receive automated feedback on their configurations, including annotations of critical configuration errors. But SQL Server 2008 R2 BPA doesn't just tell you that something is wrong -- it gives you the needed information and links to help you fix the problem.
Top free Microsoft server tools: SQL Server Migration Assistant
Microsoft offers two Migration Assistants helpful for bringing an existing database into SQL: one for MySQL, and one for Access. The SQL Server Migration Assistant (SSMA) for MySQL will help you migrate any MySQL 4.1 and higher database to SQL 2005/2008/2008 R2 and SQL Azure, enabling you to convert your MySQL schemas to SQL Server schemas, upload the schemas to SQL, and migrate your data to the new SQL database. The Access version does pretty much the same thing, converting Access database objects to SQL database objects, loading them into SQL, and then migrating the data. One nice feature to the Access SSMA is that you can continue to use Access as your front-end application through links from Access tables to SQL Server tables.
