Duplicate Name exists on the network

Discussion in 'Active Directory' started by Gareth Saunders, Jun 16, 2006.

  1. Hi There

    I have a laptop that is behaving very strangely.

    It used to be a member of the domain, but has been taken off (removed from
    AD and all DNS records deleted). However, when powering on the laptop, I am
    receiving a message saying theat a Duplicate Name exists on the network. I've
    run searches and not been able to find anything on any part of our network to
    suggest why. Any help would be appreciated!!

    The other problem is when attempting to shut down or restart, the laptop
    goes through it's motions of shutting down, but then all that is left is a
    frozen cursor and a blue screen. The only way out of this is to physically
    power it off.

    Many thanks in advance

    Verify that the computers domain account was removed when the computer was
    taken out of the domain. If it wasn't you will have to delete it manually.

    disconnect the laptop and ping the computer name from other machine and
    check if replies.

    I hope that the information above helps you

  4. Hi

    I have already manually deleted the AD enty, checked that the DHCP entry has
    been deleted and it has been deleted from both the forward and reverse lookup
    zones from DNS.

    Any further suggestions?

    Kind Regards

  5. the error is an NetBIOS error, not an DNS error. Check your WINS for
    duplicate Names. Does the Notebook have more than one networkcard?
