    The local computer object has System permissions on the local computer, which grants all permissions locally. For example, a Startup script runs with System privileges and can modify the local registry and local files and install software. The computer object uses the credentials of the AD computer object elsewhere in the domain. There is no need to make the AD computer object, or the local computer object, a member of the local Administrators group.

    I should add, if the aim is to make all domain users that logon to the computer local Administrators (which is not recommended), their are better solutions. I would recommend making all users members of a domain group, such as LocalAdms (you could also use the group "Domain Users", but I'd rather limit this to specified users of your choice). Then use the Restricted Groups feature of a GPO to specify this group as a member of all local Administrator groups on all computers in the domain. For more on Restricted Groups, see these links:

    Agree with Richard that if you would like to make domain users that logon to the computer to be local Administrators, you can use the feature "Restricted Groups" in Group Policy. Here is another article which might be helpful for you:

    You can configure specific group in AD that can be nested to the local administrators group on every workstations added to the domain. Users, which you will put there, have local administrator rights. So you can do it via group policy, Computer Configuration\Windows Settings\Restricted Groups.

    If you need to add users to local administrators groups only on a specific computer, you can do it manually via Computer Management on the workstation.

    Add a computer which joined domain to its own local admin group. will any users login on this computer be local administrator of this computer?

    as the title

     

    Do you mean adding Domain User(Duser) to Local Administrators Group?

    Follow these Steps:

    1. Create a text file and name it CompList.txt

    2. Put all the client computer names in it.

    3. Next, run the following command:

    Psexec.exe -@CompList.TXT Net LocalGroup Administrators DomainName.COM/Duser /add

    The above command runs against each computer mentioned in the CompList.TXT and adds the Duser to Local Administrators Security Group. 

    You can download the Psexec.exe from here: http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

    Thanks

    You couldn't add a computer to local administrators group. As I know.

    What I mean is I add the computer name to local admin group. Then will all domain users  login to this computer  be local admin of this computer.  I don't need to add domain user to its local admin group. I would like to know if it is right.
