  • Hi,

    Are the BUILTIN\Administrators found in the Logins? What kind of change you want to make for this account?

    As far as I know, the BUILTIN\Administrators is the default group in AD. It is added as a windows login in SQL Server 2008. If you want to change the members inside the group, you need to modify it in Active Directory. If you want add more logins, you can add a new login.

  • Hi Dildar,

    SharePoint have the feature to change the service account, for example the user login was expired at AD, and need to be updated, then we can update this by updatefarmcredentials.:

    Based on your enquiry, builtin/administrator is a default user login that being added, but, sharepoint 2007 is using service account to make the connections to the SQL. if you use this builtin/administrator at your farm as service account, then you remove it, it will have impact. so its better to add another service account first then you edit/remove the builtin/administrator.

    it is suggested that not to remove this builtin/administrator, but add another service account to be a service account.

    here is some article regarding the user login :

  • Hi DILDAR,

    No, you cannot rename the Builtin\Administrators Security Group but the Builtin\Administrators can be removed from SQL Server.

    The Builtin\Administrators Group is a Legacy Group that you find on DCs, it is the equivalent of a Domain Admin when used on DCs. However, it is not added to the Local Servers Administrators Group like the Domain Admin group is.

    Kids know that most people never look in their Builtin\Administrators group and will sometimes add their username into this group which is essentially Domain Admin but only on other DCs.

    Note: you can not add the Builtin\Administrators group to a SQL Server that is not installed on a DC, it doesn't exist.

    However, please read the next steps below prior to removing the BUILTIN\Administrators group from SQL Server.

    Next Steps
    1. Verify that you know the "sa" password by logging into the SQL Server with the "sa" account with either Query Analyzer or Management Studio on the SQL Server you want to modify.
    2. Validate other Windows groups or Windows logins are assigned SQL Server System Administrator rights on this SQL Server.
    3. Review the rights assigned to the BUILTIN\Administrators group.
    4. Research the members of the Windows Local Administrators group.
    5. If necessary, create the additional logins and groups in Active Directory and assign rights in SQL Server to ensure a minimum of 1 login and/or the "sa" login has SQL Server System Administrator rights.
    6. Validate that the members of the BUILTIN\Administrators group do not own any databases, objects, Jobs, etc and that none of the logins are connected to SQL Server.

    *** WARNING *** - Do not remove the BUILTIN\Administrators group from SQL Server if other logins or groups do not have SQL Server System Administrator rights or if you do not know the "sa" password.

    Using a SQL Query

    DROP LOGIN [BUILTIN\Administrators]

    OR using the GUI

    1. Open SSMS (SQL Server Management Studio > Go to the Security folder >
    2. Expand (+) the Logins folder, find the BUILTIN\Administrators Group
    3. Right click on the BUILTIN\Administrators group and select the Delete
    4. Confirm and if you agree and press 'OK'.
    5. Refresh, to verify the login has been dropped.

  • Thanks all of you I removed account in my test environment and MOSS 2007 stopped running and after reading some blogs i was trying to back this account but i was surprised it's not recovered, that’s why i am worry to delete this account from my live environment. What you all suggest me. <o:p></o:p>

    One more thing I want to ask is any security issue if we don’t delete BUILT account. <o:p></o:p>

  • If SharePoint stopped working did you review the rights assigned to the BUILTIN\Administrators group in the Group??

  • I will repeat the question. Did you add the users to a different group with the same permissions and remove the group or did you remove the group and nothing else. if there are users in the group with user rights to SharePoint then they will need the same rights after you remove the group...
