You must install Microsoft SQL Server on the computer that will host the Monitoring Server database. This can be the same computer that runs Monitoring Server, or a dedicated database server. Ensure that you have either SQL Server 2008 (32-bit or 64-bit) or SQL Server 2005 with Service Pack 2 (32-bit or 64-bit). For details about SQL Server, see the SQL Server TechCenter at http://go.microsoft.com/fwlink/?LinkId=129045 .
