A TechNet documentation has the information about configuring a remote instance of SQL server for VMM, or check the step by step instructions on how to perform this operation below. These steps apply to SQL Server 2005 and will walk you through a specific example. It includes the whole process from the empty database creation in SQL server to VMM setup so that you can see the entire picture and granular permissions that are required," revealed Microsoft.
