BUILTIN\Administrators Group

I have noticed that in all of the SQL 2008 installs whichwe have been performing that there was no BUILTIN\Administrators group being installed.

Has this Login gone away? It used to be automatically installed with SQL 2005

It is no longer added automatically. If you want to add the group you can during setup or afterwards, but this was done for increased security out of the box and to make it more explicit who is an SYSADMIN in SQL and who isn't.

The local Windows Group BUILTIN\Administrators is not included in the SQL Server sysadmin server role andis not added as a login account unless during setup or at later time a sysadmin specifically adds the windows group.

However, for disaster recovery purposes, BUILTIN\Administrators can connect to SQL Server and are treated as sysadmins when SQL Server is started with the -F flag (a disaster recovery only mode).

Hi Jack,

Based on the CTP's and BOL, I thought the group was added by default, however, it was nolonger associated with sysadmin group. Did that change with RC0?

SQL Server 2008 Books Online (February 2008)

SQL Server 2008 Security Changes

The local Windows Group BUILTIN\Administrator is no longer included in the SQL Server sysadmin server role.

Thanks for clarifying as I don't have a system infront of me.

(While members of the Administrators local group are members of the Server role, their membership in the Server role is not visible in the user interface.)

I just got this from the May 2008 BOL which is the same as 2005 so they question is why only the relational engine and not Analysis Service because I just gave a hack to a user to remove these groups in another forum? Windows System Admins are in most cases clueless about what goes on Analysis Services so whose idea is it to give clueless people total control of something they don't know?

Jack,
Do you know if the application of Windows 2003 SP2 modifies the builtin administrators group permissions in any way?
