Select the Accounts for SQL Instance Administration
In SQL Server 2005, the Windows Builtin\Administrator local group was automatically
given administrative permissions for the SQL instance. This is no longer the case with
SQL Server 2008. Instead, when you install an instance, you will need to specify the
users and/or groups that should have administrative permissions for the instance.
On the following dialog, select the accounts that should have administrative privileges
for the SQL instances you are installing.
Click Add to open the Select Users or Groups dialog.
