Computer is on the domain but there is no computer object in the directory. RRS feed

  • Question

  • Hi,

    I have come across this problem a lot.

    Where you add a computer to the domain and everything works fine.

    The user can login and all appears to be well. But, if I go to move the Computer I find that it's hasn't come across.

    It must be somewhere because it continues to work, but nothing comes up when you search the directory.

    It's not in the old, computers, or any other container that I can see.

    But, if I de-join and re-join the machine it will come across, and this is something that I don't want to be doing for our machines.

    Please can you help.

    Thanks

    I would recommend to redirect the newly created computers to a different OU in order to make sure that you know where the default place is for newly created computers using Redircmp.

    Also enable auditing and trace down related events for the computer deletion in the OU. The link "Tracing down user and computer account deletion in Active Directory" may be useful.

    What do you see if you query the computers using Powershell or dsquery?

    I found this similar problem.

    He never got to the bottom of it.

    Similar problem

    Well, he did - he just had more work than he would have liked.:

    "After manually rejoining the computer to our domain it showed correctly in the computer container of Active Directory. I had no errors but I didn't really expect to either I knew this would fix the problem I just didn't want to have to physcially go to all these locations and manually touch all the computers. I compiled a list yesterday comparing AD computers with our inventory and close to 50 computers are not showing in AD. That means alot of time wasted for me :(

    Thanks for the help though everyone who contributed thoughts and suggestions. It was good to confirm what I need to do. Now I just got to man up and do it :)"

  • Otherwise... (just tried this, based on what Florian suggested in the other post), you can try this:

    gpresult /r /scope computer

    If you look at the output, under "COMPUTER SETTINGS" you should see the container:

    My computer would be located here (if I worked for contoso):

    COMPUTER SETTINGS
    ------------------
        CN=CMP123,OU=Workstations,DC=contoso,DC=com

  • Use "Find" to retrieve your computer. Unless you moved computer to another OU, it should stay in default place or better in default organization unit.

    It is not clear what you did and you have given too few information to give more advice.

  • When you do your search, make sure in the Find option at the top of the search window you have seleted "Computer" objects.  If you don't select computers it won't show you they exist.  Another thing you want to do in Active Directory Usersw and Computers (ADUC) is to select the domain and then at the top of the Menu select View and then Advanced.  Once you find a computer in the Find function, you can dobule click on it and then select the "Object" tab which will then show you the root container for the object.

  • Hi,

    Maybe I didn't explain this myself too well.

    I am using the find facility and searching for Computer objects.

    I have the advanced view of AD on.

    The Computer object was removed from the Domain and the device was re-joined to the Domain.

    The user can login on the device, but the device is not showing up in AD.

    It doesn't exist in a search, but it has to be there, or else he wouldn't be able to login.

    I have seen this behaviour on more than one domain in different organisations.

    You have to de-join the machine again and re-join it for the obj to appear.
